Water → 1-(Morpholin-4-ylcarbonyl)-5-[4-(trifluoromethyl)phenyl]piperidine-3-carboxamide

Participants

Reaction Steps

At 0° C., 0.56 g (5.52 mmol) of triethylamine and 0.55 g (3.70 mmol) of morpholine-4-carbonyl chloride were added to a solution of 0.61 mg (1.85 mmol) of 5-[4-(trifluoromethyl)phenyl]piperidine-3-carboxamide acetate (Example 51A) in 10 ml of dichloromethane. The reaction mixture was stirred at RT for 1 h. After addition of water and phase separation, the organic phase was dried over sodium sulphate, filtered and concentrated under reduced pressure. This gave 0.61 g (100% of theory) of crude product in a purity of 77% (LC-MS), which was reacted without any further purification steps.
