Reaction Steps

5-((Benzyloxy)methyl)-2-butyl-4-chloro-7-iodo-5H-pyrrolo[3,2-d]pyrimidine (1 g, 2.2 mmol) was suspended in 2-propanol (5 mL) and 35% (0.88) ammonia solution (4 mL). The reaction was stirred at 120° C. for 90 minutes in a Biotage Initiator microwave. A further 1 mL of 35% (0.88) ammonia solution was added to the reaction. The reaction was stirred at 120° C. for 90 minutes in a Biotage Initiator microwave. The reaction was evaporated in vacuo to yield a pale yellow oil. The oil was dissolved in the minimum volume of 20% methanol in dichloromethane and purified by chromatography on silica using a gradient of 0-100% ethyl acetate in cyclohexane gradient over 80 minutes. Fractions were combined and evaporated in vacuo to yield the title compound as a colourless oil (768 mg).
