Reaction Steps

To N-benzyl(methoxy)-N-((trimethylsilyl)methyl)methanamine (1.7 g, 7.0 mmol) and 1-(4-trifluoromethoxy-phenyl)-5,6-dihydro-1H-pyridin-2-one (0.6 g, 2.3 mmol) in DCM (30 mL) was added a solution of trifluoroacetic acid (0.026 g, 0.23 mmol) in DCM (10 mL) at 4° C. After the mixture was stirred at 50° C. for 3 h, the solution was washed with saturated sodium bicarbonate and brine, then dried over anhydrous Na2SO4. After removal of the DCM, the residue was purified by column chromatography on silica gel with petroleum ether/ethyl acetate P (10:1 to 5:1) to yield the title compound (0.19 g, 21%). 1H NMR (300 MHz, CDCl3): δ 7.34-7.20 (m, 9H), 3.77-3.55 (m, 4H), 3.18-3.01 (m, 2H), 2.93-3.83 (m, 3H), 2.43-2.41 (m, 1H), 2.07-2.05 (m, 1H), 1.80-1.75 (m, 1H); LC-MS: [M+1]+ 391.1.
