Procedure

A solution of 3-methyl-1-(4′-(trifluoromethyl)biphenyl-4-yl)butan-1-amine (0.200 g, 0.651 mmol), methyl 5-chloropyrazine-2-carboxylate (124 mg, 0.716 mmol), and diisopropylethylamine (168 mg, 1.30 mmol) in 2-propanol (5 mL) was heated in a microwave reactor at 100° C. for 2 h. The mixture was cooled to room temperature and concentrated. The mixture was concentrated and purified by column chromatography to give methyl 5-(3-methyl-1-(4′-(trifluoromethyl)biphenyl-4-yl)butylamino)pyrazine-2-carboxylate (150 mg, 52%).
