tert-butyl N-(4-[[6-(propan-2-yl)thieno[2,3-d]pyrimidin-4-yl]oxy]cyclohexyl)carbamate → 4-[[6-(Propan-2-yl)thieno[2,3-d]pyrimidin-4-yl]oxy]cyclohexan-1-amine

Reaction Steps

To a 100-mL round-bottom flask was added a solution of tert-butyl N-(4-[[6-(propan-2-yl)thieno[2,3-d]pyrimidin-4-yl]oxy]cyclohexyl)carbamate (4.8 g, 12.26 mmol, 1.00 equiv) in dichloromethane (100 mL). Hydrogen chloride was bubbled through the solution. The resulting solution was stirred for 5 h at 0-10° C. The resulting mixture was concentrated under vacuum. This resulted in 3.6 g (90%) of 4-[[6-(propan-2-yl)thieno[2,3-d]pyrimidin-4-yl]oxy]cyclohexan-1-amine hydrochloride as a yellow solid. MS: m/z 292 (M+H)+.
