반응 단계
To a stirred solution of 2,2-dimethyl-5-[2-(2-aminopurin-9-yl)ethyl]-1,3-dioxane (1 g) in a mixture of tetrahydrofuran (20 ml) and methanol (6 ml) at room temperature was added concentrated hydrochloric acid (0.32 ml). The resulting mixture was stirred for 2 hours during which time a solid crystallised. The solid was collected by filtration, washed with tetrahydrofuran (2 ml) and dried under a flow of air to give the desired product as the hydrochloride salt (800 mg, 81% yield).
