To a mixture of 2-chloropropionaldehyde dimethyl acetal (5.84 g, 42.1 mmol) in H2O (26 mL) was added conc. HCl (1 mL). After heating at 95° C. for 15 min (or until the solution turns homogenous), NaOAc (5.2 g) was added to neutralize the excess HCl. The resulting solution was then transferred to a separate flask containing a suspension of 6-aminouracil (4 g, 31.5 mmol) and NaOAc (2.6 g) in H2O (52 mL). After heating the mixture at reflux overnight, the reaction was cooled and the precipitates were collected by filtration to give 5-methyl-7H-pyrrolo[2,3-d]pyrimidine-2,4-diol (4.8 g, 94% yield).
