Reaction Steps

A solution of (6-(difluoromethoxy)pyridin-2-yl)methanol (250 mg; 1.42 mmol) in anh. DCM (12 ml) was treated at rt with CBr4 (473 mg; 1.42 mmol), and with PPh3 (374 mg; 1.42 mmol). The resulting mixture was further stirred at rt, under nitrogen, for 1 h. Concentration to dryness under reduced pressure, and subsequent purification by FC (DCM) afforded 2-(bromomethyl)-6-(difluoromethoxy)pyridine as a yellow oil which was directly used for the next reaction. LC-MS (conditions D): tR=0.95 min.; [M+H]+: 237.82 g/mol.
