Reaction Steps

A solution of 1.26 g (3.55 mmol) [6-chloro-4-(2-chloro-phenyl)-pyridin-3-yl]-methyl-carbamic acid tert-butyl ester and 3.34 ml (42.8 mmol) trifluoroacetic acid in 11 ml dichloromethane was stirred at room temperature for 2 h. Addition of 2 M aqueous sodium carbonate solution was followed by extraction with two portions of dichloromethane. The combined organic layers were dried with sodium sulfate and concentrated to give 0.89 g (99%) of the title compound as an off-white solid.
