(5-methyl-1H-imidazol-4-yl)methyl[4-[4-(methylsulfonyl)phenyl]-6-(trifluoromethyl)pyrimidin-2yl]formamide → N-[(5-methyl-1H-imidazol-4-yl)methyl]-4-[4-(methylsulfonyl)phenyl]-6-(trifluoromethyl)pyrimidine-2-amine

Participants

Reaction Steps

A solution of crude (5-methyl-1H-imidazol-4-yl)methyl[4-[4-(methylsulfonyl)phenyl]-6-(trifluoromethyl)pyrimidin-2yl]formamide (0.27 g, 0.615 mmol) in ethanol (10 ml) and 2N hydrochloric acid (10 ml) was heated under reflux for 2 h. The solvents were then evaporated and the residue basified with 0.880 ammonia and extracted with DCM. The dried organic phase was evaporated onto silica gel and this mixture was purified on a silica gel SPE cartridge. Elution with DCM:ethanol:0.880 ammonia, 91:8:1, gave the title compound as a colourless crystalline solid (0.14 g).
