To a cooled (0° C.) solution of (2-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)pyridin-3-yl)methanol (0.070 g, 0.32 mmol) in dichloromethane was added SOCl2 (0.23 mL, 3.2 mmol) and the reaction mixture was allowed to warm to ambient temperature. After 1 h, the reaction mixture was concentrated and azeotroped with toluene three times to provide 3-(3-(chloromethyl)pyridin-2-yl)-8-oxa-3-azabicyclo[3.2.1]octane (0.075 g, 98%) as a clear oil. MS (ES) for C12H15ClN2O: 239 (MH+).
