Procedure

A mixture of 5-bromo-6-chloro-N-(4-(trifluoromethoxy)phenyl)nicotinamide (Stage 12.2, 237 mg, 0.60 mmol), 3-(methylamino)propan-1-ol (64 mg, 0.72 mmol), iPrOH (2.4 mL) and DIPEA (0.205 mL, 0.155 g, 1.2 mmol) were subjected to MW irradiation at 140° C. for 3 h. The vial was cooled to RT and the RM was evaporated to dryness under reduced pressure. No further purification was required to afford the title compound in an equimolar mixture with DIPEA hydrochloride. LC-MS (Condition 5) tR=1.18 min, m/z=448.0 [M+H]+, m/z=446.0 [M−H]−.
