Reaction Steps

To a solution of tert-butyl 4-(3-(4-amino-5-((benzyloxy)methyl)-2-butyl-5H-pyrrolo[3,2-d]pyrimidin-7-yl)prop-2-yn-1-yl)piperazine-1-carboxylate (85 mg, 0.160 mmol) in anhydrous methanol (5 mL) was added 4M hydrogen chloride in 1,4-dioxane (0.5 ml, 2.0 mmol). The reaction was stirred at room temperature for 19 hours. A further 0.5 mL (2.0 mmol) of 4M hydrogen chloride in 1,4-dioxane was added to the reaction. Reaction stirred at room temperature for 2 hours. The reaction was evaporated to dryness under a stream of nitrogen to yield a green oil. The oil was dissolved in MeOH:DMSO (1:1) (2×1 mL) and purified by MDAP (Method B). Appropriate fractions were combined and evaporated in-vacuo to yield the title compound as a pale yellow oil (38 mg).
