To a microwave vial were charged N-[(1S,2S)-2-Aminocyclopentyl]-2,6-dimethoxybenzamide hydrochloride (Intermediate 5; 80 mg, 0.266 mmol) in dry NMP (1 ml). To this was then added DIPEA (138 μl, 0.798 mmol) and 2-fluoro-6-(trifluoromethyl)pyridine (CAS number 94239-04-0; 53 mg, 0.319 mmol). The reaction was subjected to microwave irradiation at 200° C. for 30 minutes and then at 250° C. for 20 minutes. The reaction mixture was directly purified by reverse phase preparative HPLC (eluted with acetonitrile/water containing 0.1% ammonia) to afford the title compound.
