Reaction Steps

To a solution of tert-butyl N-[2-(4-[[4-(dimethylamino)cyclohexyl]oxy]thieno[2,3-d]pyrimidin-6-yl)ethyl]carbamate (140 mg, 0.33 mmol, 1.00 equiv) in 5 mL of DCM was added CF3COOH (0.5 mL) at room temperature. The resulting solution was stirred for 5 h at ambient temperature and then concentrated under vacuum to give the desired 4-[[6-(2-aminoethyl)thieno[2,3-d]pyrimidin-4-yl]oxy]-N,N-dimethylcyclohexan-1-amine trifluoroacetate (100 mg) as a yellow oil which was used directly without further purification.
