실험 절차

3-[(Dimethylamino)methylene]-1-methylpiperidin-4-one (9.04 g, 53.7 mmol) and tert-butyl {(3R)-1-[amino(imino)methyl]pyrrolidin-3-yl}carbamate hydrochloride (14.2 g, 53.7 mmol) were dissolved in methanol (100 mL) and to this was added dropwise sodium methoxide (9.66 g of a 30% solution in methanol). The reaction mixture was refluxed for 3 hours and then cooled to room temperature. The reaction mixture was then evaporated to dryness, and the residue was treated with water (50 mL). The precipitate was separated by filtration, washed with water (25 mL) and diethyl ether (50 mL) and dried to give the title compound 10.43 g (yield 58%).
