Procedure

1.00 g (4.26 mmol) (3-chloro-phenyl)-difluoro-acetic acid ethyl ester (prepared according to the procedure described in WO 2006/122788) were dissolved in 100 ml of methanol and treated in an ice bath with 120 mg (0.75 mmol) of sodium borohydride. After stirring overnight the mixture was evaporated and the residue was purified by silica gel chromatography (DCM/methanol 98:2) to give 700 mg of the title compound.
