Reaction Steps
A mixture of 5-bromo-2,3-difluoropyridine (Matrix, Columbia, USA, 2.53 mmol) and 8 M methylamine in EtOH (Aldrich, Buchs, Switzerland, 2 ml, 16 mmol) was sealed in a vial and heated with microwave irradiation at 100° C. for 30 min. The cooled RM was diluted with EtOAc, washed with brine, dried over Na2SO4, filtered and evaporated to dryness to give the title product as an off-white solid. (HPLC: tR 1.94 min (Method A); M+H=205, 207, M−H=203, 205 MS-ES)
