Reaction Steps

3-(RS)-Amino-1,3-dihydro-5-(2-fluorophenyl)-2H-1,4-benzodiazepin-2-one (75 mg, 0.229 mmol), thiophene-3-carbonyl chloride (44.9 mg, 0.306 mmol) and triethylamine (42.5 μl, 0.306 mmol) were combined in CH2Cl2 (4 ml) and stirred 10 min. at 25° C. The reaction was concentrated and chromatographed on silica gel (2% MeOH in CH2Cl2) to give the title compound as a white solid from Et2O: (m.p. 238°-239°).
