Participants

Reaction Steps

To a 25 ml round bottom flask was added tert-butyl 4-(1-methyl-1-{[6-(trifluoromethyl)pyridin-2-yl]sulfonyl}ethyl)piperidine-1-carboxylate (0.806 g, 1.85 mmol), trifluoroacetic acid (1.5 ml) and dichloromethane (5 ml). The resulting solution was stirred at room temperature for 1 hour. It was diluted with 50 ml ethyl acetate, washed with 50 ml 10% KOH and then 30 ml brine. The organics were dried over sodium sulfate, filtered and concentrated to give 0.33 g desired product as cyrstalline solid.
