Procedure

To a stirred solution of (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(diphenylmethyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylic acid (142 mg) in DMF (3 mL) was added O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (67 mg), HOBT (77 mg), and EDCI hydrochloride (109 mg), and the resulting mixture was stirred at ambient temperature for 7 hours. The reaction mixture was diluted with ethyl acetate and washed successively with water, saturated NaHCO3 solution, and brine. The organic phase was dried over Na2SO4 and concentrated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform:methanol=5:1) to give tert-butyl [(3R)-1-(diphenylmethyl)-3-pyrrolidinyl](5-{(1E)-3-oxo-3-[(tetrahydro-2H-pyran-2-yloxy)amino]-1-propen-1-yl}-2-pyridyl)carbamate (100 mg) as a pale yellow oil.
