合成路线1
该中间体在本合成路线中的序号:(IX)Alkylation of benzodiazepinone (I) with 3-(chloromethyl)- pyridine (II) in the presence of NaH gave the 1-substituted benzodiazepinone (III). Reduction of the amide group of (III) with borane in THF afforded benzodiazepine (IV). Subsequent condensation with 4-nitrobenzoyl chloride (V) gave nitrobenzamide (VI), which was reduced to amine (VII) by hydrogenation in the presence of Pd/C. This compound was coupled with acid chloride (IX) (prepared by treatment of 2-phenylbenzoic acid (VIII) with oxalyl chloride) to yield the title compound.

该中间体在本合成路线中的序号:(XVI)The bromination of 1-(p-toluenesulfonyl)-2,3,4,5-tetrahydro-1H-1-benzazepin-5-one (IX) with Br2 in CHCl3 gives the alpha-bromo ketone (X), which is cyclized with acetamidine hydrochloride (VIII) by means of K2CO3, yielding the expected imidazo-benzazepine (XI).

合成路线4
该中间体在本合成路线中的序号:(IX)Title compound has been obtained by two synthetic procedures: 1) Pyrrole-2-carbaldehyde (I) was alkylated with 2-nitrobenzyl bromide (II) in the presence of NaH to afford the N-nitrobenzyl pyrrole (III). Then, reductive cyclization over Pd/C produced the pyrrolobenzodiazepine (IV). Subsequent condensation of (IV) with acid chloride (VI), prepared from 3-methoxy-4-nitrobenzoic acid (V) and oxalyl chloride, gave benzamide (VII). The nitro group of (VII) was then reduced by catalytic hydrogenation over Pd/C, and the resulting amine (VIII) was further acylated with biphenyl-2-carbonyl chloride (IX) in the presence of diisopropyl ethylamine (DIEA) to yield diamide (X). Finally, the Mannich reaction with tetramethyl diaminomethane and paraformaldehyde introduced the (dimethylamino)methyl group into the pyrrole nucleus. 2) In a related procedure, 3-methoxy-4-nitrobenzoic acid (V) was esterified with MeOH in the presence of SOCl2. The nitrobenzoic ester (XI) was reduced to aminoester (XII) by hydrogenation over Pd/C, and then acylated with biphenyl-2-carbonyl chloride (IX) and DIEA to produce amide (XIII). Subsequent saponification of the ester function of (XIII), followed by treatment with oxalyl chloride furnished acid chloride (XIV), which was then condensed with the tricyclic intermediate (IV) to yield diamide (X). Finally, the (dimethylamino)methyl group was introduced, as before, by means of a Mannich reaction.

合成路线6
该中间体在本合成路线中的序号:(XII)Tetrahydrobenzothiophene-4-one (I) was treated with hydroxylamine to afford oxime (IIa-b) as a mixture of syn and anti isomers, which were condensed with tosyl chloride yielding the oxime O-tosylate (IIIa-b). Beckmann rearrangement of (IIIa-b) in the presence of KOAc gave rise to lactam (IV), and subsequent reduction with borane provided thienoazepine (V). Condensation of (V) with 2-chloro-4-nitrobenzoyl chloride (VI) gave amide (VII). A 7-oxo group was introduced by oxidation of (VII) with KMnO4 in acetone-water. The resulting ketone (VIII) was treated with Bredereck’s reagent to afford the dimethylaminomethylene ketone (IX). Cyclization of (IX) with hydrazine produced the tricyclic compound (X). The nitro group of (X) was then reduced to amine (XI) using stannous chloride. Coupling of (XI) with 2-biphenylcarbonyl chloride (XII) furnished the diacylated derivative (XIII). Finally, selective monodeacylation of(XIII) with NaOH yielded the title compound.
