Cesium carbonate → 5-((4-(tert-butyldimethylsilyloxy)phenoxy)methyl)-N-(3,4-dichlorophenyl)pyrimidin-2-amine

Participants

Reaction Steps

A mixture of 4-((tert-butyldimethylsilyl)oxy)phenol (0.086 g, 0.381 mmol), Cs2CO3 (0.186 g, 0.572 mmol) and 5-(chloromethyl)-N-(3,4-dichlorophenyl)pyrimidin-2-amine (0.110 g, 0.381 mmol) in DMF (3.8 mL) was stirred at room temperature for 18 h. The reaction mixture was concentrated and purified by flash chromatography on silica gel using 10-50% ethyl acetate in hexanes. The desired fractions were concentrated to give 5-((4-(tert-butyldimethylsilyloxy)phenoxy)methyl)-N-(3,4-dichlorophenyl)pyrimidin-2-amine as a yellow solid (0.022 g, 12%). LCMS: R.T.=3.73 min; [M+H]+=476.23
