実験手順

A mixture of 3-bromo-5-fluoropyridine (Frontier Scientific, Logan, USA, 5.63 mmol) and cyclobutylamine (Fluka, Buchs, Switzerland, 12.38 mmol) in NMP (8 ml) was heated under microwave irradiation for 1 h at 190° C. and for 5.5 h at 200° C. The reaction mixture was diluted with EtOAc and washed with saturated aqueous NaHCO3, with brine (3×), dried over Na2SO4, filtered, evaporated and dried under vacuum to give the title compound as an off-white solid. (HPLC: tR 2.31 min (Method A); M+H=227, 229 MS-ES)
