Dimethylformamide → tert-Butyl 4-(5-((4-(2-(1-carbamoylcyclopropyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)pyridin-2-yl)piperidine-1-carboxylate

Participants

Reaction Steps

DMF (3 mL) and Et3N (0.30 mL) were added to a mixture of tert-butyl 4-(5-((4-((2-(1-carbamoylcyclopropyl)phenyl)ethynyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)pyridin-2-yl)piperidine-1-carboxylate A78 (0.118 g, 0.194 mmol) and 10% Pd/C (0.182 g). The mixture was stirred under a hydrogen atmosphere for 20 hours, filtered through Celite and the filtrate concentrated under reduced pressure. Purification by silica gel column chromatography (0-100% EtOAc in Petroleum Benzine 40-60° C.) gave the title compound A79 (0.080 g, 67%). LCMS-A: rt 5.852 min; m/z 611.3 [M+H]+.
