Procedure

To a solution of (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(3-fluorobenzyl)-3-pyrrolidinyl]amino}-3-pyridyl)acrylic acid (2.25 g, crude) in DMF (23 mL) was added was added O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (776 mg), HOBt (1.03 g), and EDCI (1.19 g) and the resulting mixture was stirred at ambient temperature for 3 hours. The reaction mixture was diluted with water and extracted with AcOEt. The organic phase was washed with sat NH4Cl aq solution, sat NaHCO3 aq solution, and brine, and dried over Na2SO4. The solvent was removed in vacuo and the residue was purified by silica gel column chromatography eluted with AcOEt to give tert-butyl [(3R)-1-(3-fluorobenzyl)-3-pyrrolidinyl](5-{(1E)-3-oxo-3-[(tetrahydro-2H-pyran-2-yloxy)amino]-1-propen-1-yl}-2-pyridyl)carbamate (2.51 mg) as pale yellow form.
