Reaction Steps

To a solution of tert-butyl ((1S,3R)-3-((2-chloro-4-methoxypyrimidin-5-yl)ethynyl)cyclohexyl)carbamate (Q2, 118 mg) in 1,4-dioxane (3 mL), a 4.0 mol/L solution of hydrochloric acid in 1,4-dioxane (3 mL) was added at room temperature, and the mixture was stirred at the same temperature for 1 hour. To the reaction mixture, a 4.0 mol/L solution of hydrochloric acid in 1,4-dioxane (3 mL) was added at room temperature, and the mixture was stirred at the same temperature for 50 minutes. The solvent was evaporated under reduced pressure to obtain (1S,3R)-3-((2-chloro-4-methoxypyrimidin-5-yl)ethynyl)cyclohexaneamine (Q3) hydrochloride.
