Procedure

A solution of (3R) 3-amino-2-oxo-5-phenyl-1-(2,2,2-trifluorethyl)-2,3-dihydro-1H-1,4-benzodiazepine (0.030 g, 0.090 mmol) and 4-nitrophenylchloroformate (0.018 g, 0.090 mmol) in dry tetrahydrofuran (0.5 mL) was cooled to 0° C. under argon. Triethylamine (0.013 mL, 0.090 mmol) was added and the reaction stirred for 1 h. A solution of 2-oxo-1-(4-piperidinyl)-2,3-dihydro-1H-imidazol[4,5-c]pyridine dihydrobromide (0.034 g, 0.90 mmol) and triethylamine (0.065 mL) in dimethylsulfoxide (0.5 mL) was added. The reaction was allowed to come to room temperature and stirred until complete. The crude product was purified by reverse phase HPLC (C-18, 5% to 95% 0.1% trifluoroacetic acid/acetonitrile in 0.1% aqueous trifluoroacetic acid gradient elution) to give the title compound (0.028 g, 45% yield). MS 578.2108 (M+1)
