Versuchsvorschrift

A solution of (3R) 3-amino-2-oxo-5-phenyl-1-(2,2,2-trifluorethyl)-2,3-dihydro-1H-1,4-benzodiazepine (Y.-J. Shi et al., Tetrahedron, 1999, 55, 909-918) (0.150 g, 0.45 mmol) and 4-nitrophenylchloroformate (0.091 g, 0.45 mmol) in dry tetrahydrofuran (2.5 mL) was cooled to 0° C. under argon. Triethylamine (0.063 mL, 0.45 mmol) was added and the reaction stirred for 1 h. A solution of 2-oxo-1-(4-piperidinyl)-2,3-dihydro-1H-imidazo[4,5-b]pyridine dihydrochloride (0.130 g, 0.45 mmol) and triethylamine (0.190 mL) in dimethylsulfoxide (2.5 mL) was added. The reaction was allowed to come to room temperature and stirred overnight. 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). The pure fractions were extracted with methylene chloride and saturated sodium bicarbonate. The organic layer was dried, filtered and evaporated. The product was taken up in methanol and treated with hydrogen chloride. The solvent was evaporated and the resulting solid was dried in vacuo, to yield the title compound (184 mg, 66% yield).
