Reaction Steps

According to Process F, a mixture of {1-[Isopropyl-(4-methoxy-phenyl)-carbamoylmethyl]-2-oxo-5-phenyl-2,3-dihydro-1H-benzo[e][1,4]diazepin-3-yl}-acetic acid (200 mg, 0.400 mmol), prepared as in Intermediate 29, aniline (0.033 mL, 0.356 mmol), and bromo-tris-pyrrolidino-phosphonium hexafluorophosphate (167 mg, 0.356 mmol) in anhydrous DCM (3 mL) is treated with diisopropylethylamine (0.170 mL, 0.978 mmol) and stirred at ambient temperature under nitrogen. After 1.5 hrs., the solvent is removed in vacuo and the residue is purified by chromatography on flash grade silica gel using 60% ethyl acetate in n-hexane. Fractions containing the product are combined, concentrated in vacuo and triturated with n-hexane. After removing the solvent in vacuo, the product is dried overnight at ambient temperature under high vacuum to provide the title compound (123 mg, 0.214 mmol) as a white solid. The product is lyophilized from acetonitrile/water. 1H NMR (300 MHz, d6-DMSO) δ=0.86-0.96 (m, 6H); 3.14 (d, J=6.9 Hz, 2H); 3.77 (S, 3H); 4.03-6.12 (M, 2H); 4.23 (D, J=16.8 HZ, 1H); 4.59-6.73 (M, 1H); 6.97-7.08 (M, 3H); 7.15-7.32 (M, 6H); 7.36-7.66 (M, 9H); 10.15 (S, 1H). MS (FAB): [M+H]+ =575.
