5-(1-(t-Butoxycarbonyl)-1,2,3,6-tetrahydropyrid-4-yl)-7-(2-chloro-4-pyridyl)-8-(3-(trifluoromethyl)phenyl)-1,2,4-triazolo[4,3-c]pyrimidine (0.93 g, 1.7 mmol), (S)-α-methylbenzylamine (0.48 g, 4 mmol), palladium acetate (0.06 g, 0.26 mmol) and racemic BINAP (0.16 g, 0.26 mmol) were combined in toluene (15 ml) and the resulting solution was degassed with nitrogen. Sodium t-butoxide (0.48 g, 5 mmol) was added and the resulting mixture was heated to 90° C. for 1 hour. The mixture was partitioned between sat. ammonium chloride and ethyl acetate. The organic layer was separated, dried over sodium sulfate, filtered and concentrated to a syrup. The residue was purified by column chromatography on silica gel (30% ethyl acetate in hexane) gave the product as a syrup; MS m/z (M+H)+ 642.4; C35H34F3N7O2 require 641.3.
