Reaction Steps

A suspension of 5-bromo-4-chloro-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (17 g, 69.0 mmol) in ammonium hydroxide (150 mL, 3852 mmol) was stirred for 2 days at 100° C. in a sealed vessel. The reaction was allowed to cool to room temperature and filtered. The collected solid was washed with Et2O to afford the product 5-bromo-7-methyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (12.5 g) as a white solid.
