合成路线2
该中间体在本合成路线中的序号：(IV)The title compound has been prepared by two synthetic procedures. Condensation of 2-aminopyridine-3,5-dicarbonitrile (I) with guanidine (II) in refluxing EtOH produced the pyridopyrimidine (III). Subsequent reductive condensation of (III) with 3,4,5-trimethoxyaniline (IV) by hydrogenation over Raney Nickel provided the (arylamino)methyl derivative (V). Final reductive alkylation of (V) by means of formaldehyde and sodium cyanoborohydride then gave the target methylated amine.

该中间体在本合成路线中的序号：(IV)In an alternative synthesis, 2,4,6-triaminopyrimidine (VI) was condensed with bromomalonaldehyde (VII) under acidic conditions to give pyridopyrimidine (VIII), which was protected with pivaloyl anhydride in pyridine, yielding the bispivaloylamide (IX). Palladium-catalyzed Heck coupling of (IX) with styrene (X) afforded (XI). Subsequent ozonolysis of the styryl derivative (XI), followed by reductive workup with dimethyl sulfide gave aldehyde (XII). Reduction of (XII) to the corresponding alcohol with NaBH4, followed by bromination with PPh3 and Br2 provided bromide (XIII). The N-methyl aniline (XIV) was synthesized by direct alkylation of 3,4,5-trimethoxyaniline (IV) with methyl iodide. Nucleophilic displacement of the bromide (XIII) with aniline (XIV) afforded the tertiary amine (XV). The pivaloyl protecting groups of (XV) were finally removed by treatment with methanolic NaOMe.

Then, subsequent displacement of the remaining chlorine of pyrimidine (IV) with 3,4,5-trimethoxyaniline (V) yields the substituted pyrimidine-2,4-diamine (VI) . Condensation of pyridooxazinone derivative (VI) with di-tert-butyl chloromethyl phosphate (VII) prepared by chlorination of potassium di-tert-butylphosphate (VIII) with ClSO3CH2Cl by means of Bu4NHSO4 in CH2Cl2/H2O – in the presence of Cs2CO3 in acetone or DMF gives a mixture of three N-substituted regioisomers, which are then subjected to either column chromatography or crystallization on MTBE to provide the major N-substituted oxazinone (IX). Hydrolysis of the t-butyl ester groups of (IX) by means of AcOH in H2O or TFA in CH2Cl2 affords free acid (X) , which is finally treated with aqueous or IPA/H2O NaOH .
Alternatively, condensation of pyridooxazinone (VI) and chloromethyl phosphate (VII) with Cs2CO3 in DMAC at 40 °C affords the N-substituted oxazinone (IX), which is directly hydrolyzed by means of AcOH in H2O, and the phosphoric acid (X) is submitted to purification by crystallization on DMF .
