A mixture of 1-[4-(2,2,2-Trifluoro-ethoxy)-phenyl]-5,6-dihydro-1H-pyridin-2-one (0.27 g, 0.1 mmol), N-benzyl(methoxy)-N-((trimethylsilyl)methyl)methanamine (0.71 g, 0.3 mmol) and TFA (0.114 g, 0.1 mmol) in 20 mL of DCM was stirred at 45° C. for 30 h. The mixture was evaporated to dryness and the residue was purified by silica-gel column chromatography (eluting with petroleum ether/ethyl acetate=1:1) to obtain the title compound as colorless oil (0.125 g, 31%). LC-MS: 405.2 [M+1]+.
