Diisopropylethylamine → HCID 118162081, compound

Participants

Reaction Steps

To (4-(trifluoromethyl)pyridin-3-yl)methanamine hydrochloride (1.0 equiv.) in DMF (1.0 M) was added DIEA (2.5 equiv.). The reaction was cooled to −20° C. (ice/brine bath) then added 2,4-dichloropyrimidine-5-carbonitrile (1.0 equiv.). The reaction mixture was stirred for 10 min, then removed from the ice bath and allowed to stir for 30 min. The reaction mixture was diluted with ethyl acetate and partitioned with water. The organic layer was separated and volatile solvents were removed under reduced pressure. The residue was purified using silica gel chromatography (5-50% ethyl acetate in hexanes). The desired fractions were combined and volatile solvents were removed under reduced pressure. The residue was triturated in 10% ethyl acetate in hexanes, filtered, washed with hexanes, and dried in vacuo to afford 4-chloro-2-(((4-(trifluoromethyl)pyridin-3-yl)methyl)amino)pyrimidine-5-carbonitrile (43.0% yield) as a pale tan solid; MS (ESI) m/z 314.0 [M+1]+
