実験手順
1-(t-Butoxycarbonyl)-4-(3-oxo-3-(3-pyridyl)prop-1-enyl)piperidine (940 mg, 2.97 mmol, from Procedure 38, Step B) was hydrogenated using 5% Pd/C in 95% ethanol at atmospheric pressure. Purification by flash column chromatography on silica gel, eluting with 90:10 v/v to 50:50 v/v hexanes/ethyl acetate gave 884 mg of the title compound as a colorless syrup. For the title compound:
