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). This compound is detosylated with hot H2SO4 to provide 2-methyl-1,4,5,6-tetrahydroimidazo[4,5-d][1]benzazepine (XII). Acylation of (XII) with 4-nitroben-zoic acid (XIII) by means of pyridine in either hot MeCN or DMF affords the 6-(4-nitro-benzoyl) derivative (XIV), which is reduced with H2 and Raney-Ni in MeOH to the corres-ponding 6-(4-aminobenzoyl) compound (XV). Finally, this compound is condensed with biphenyl-2-carbonyl chloride (XVI) [ obtained by treatment of biphenyl-2-carboxylic acid (V) with oxalyl chloride in CH2Cl2/DMF] by means of pyridine in acetonitrile and treated with 4N HCl.
