실험 절차

To a solution of 500 mg (1.64 mmol) 2-(3-methoxyprop-1-ynyl)-4-methyl-6-morpholino-pyridine-3-carboxylic acid methylester in MeOH (30 ml) was added 170 mg 10%-Pd/C. The reaction solution was stirred under hydrogen atmosphere (balloon) at RT for 16 h. Then the mixture was filtered through celite and the filtrate was concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 9:1) provided 480 mg (1.55 mmol, 95%) 2-(3-methoxypropyl)-4-methyl-6-morpholino-pyridine-3-carboxylic acid methylester.
