実験手順

A mixture of (2E)-3-(6-{(tert-butoxycarbonyl)[(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid, O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (77 mg, 0.66 mmol), HOBt (89 mg, 0.66 mmol) and EDCI (126 mg, 0.66 mmol) in DMF (4.5 mL) was stirred at 0° C. for 1 hr and the mixture was stirred at ambient temperature for 18 hrs. The reaction mixture was evaporated in vacuo and the residue was partitioned between saturated sodium bicarbonate solution and EtOAc. The organic layer was separated, evaporated in vacuo. The residue was purified by preparative thin layer chromatography (chloroform-MeOH=10-1) to give tert-butyl [(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl](5-{(1E)-3-oxo-3-[(tetrahydro-2H-pyran-2-yloxy)amino]-1-propen-1-yl}-2-pyridinyl)carbamate (181 mg, 69%) as an amorphous powder.
