실험 절차

To a solution of 2-(2-ethoxyethoxy)-8-methoxy-9-(tetrahydro-2H-pyran-4-ylmethyl)-9H-purin-6-amine (240 mg) in dry methanol (10 ml) at room temperature and under nitrogen was added 4.0M hydrogen chloride in 1,4-dioxane (4.0 ml). The reaction was left to stir at room temperature for 3 hours. The reaction was neutralised by the addition of 2.0M sodium hydroxide solution and concentrated in vacuo. The residue was taken up in water (15 ml) and the solid filtered and washed with water (2×5 ml). The solid was dried en vacuo (60° C.) for 30 minutes. This afforded the title compound as an off-white solid (129 mg).
