Reaction Conditions

Reaction Steps

Triethylamine (66.5 g, 0.658 moles) was added to a solution of 4-[(1-Cyclobutyl-4-piperidinyl)oxy]aniline (81 g, 0.329 moles, obtained in preparation 1) in dichloromethane (1 L), at 0° C. under nitrogen atmosphere. Then the resulting mass was treated with a solution of chloro acetyl chloride (44.6 g, 0.395 moles) in dichloromethane (1 L) drop wise at 0° C. and stirred at 0° C. for 1 hour. The reaction mixture was washed with water, dried over sodium sulfate and concentrated under vacuum and the crude compound thus obtained was purified by flash chromatography (methanol:chloroform, 2:8) to obtain the title compound 76.1 g (Yield: 72%).
