Participants

Reaction Steps

3,4,5-Trimethoxy-N-(2-methyl-3-phenyl-allyl)-N-(2-pyrrolidin-2-yl-ethyl)-benzamide 0.11 g (2.5 mmol) and freshly distilled benzaldehyde 0.026 g (2.5 mmol) was taken in 10 ml of dry methanol. Acetic acid 0.022 ml (3.7 mmol) was added at 0° C. The reaction mixture was stirred at room temperature for 30 min and sodium cyanoborohydride 0.023 g (3.7 mmol) was added at 0° C. The reaction mixture was gradually warmed to room temperature and stirred for 14 hr. The reaction mixture was concentrated, and the residue was diluted with water and extracted with chloroform (3×20 ml). Organic layer was washed with 10% NaHCO3 solution, water and brine, dried over anhydrous sodium sulfate, concentrated and the residue was purified by column chromatography over silica gel to yield the pure desired compound. This was converted to its hydrochloride salt using dry HCl in ether to obtain 90 mg of product. Yield: 63%.
