Reaction Conditions

Reaction Steps

To a solution of crude N-(6-amino-1,3-dimethyl-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-5-yl)-2-(4-amino-phenyl)-acetamide hydrochloride salt (0.68 mmol) in methanol (35 mL) was added 10% w/v aqueous sodium hydroxide (3.4 mL) and the mixture heated to 50° C. for 7 hrs. The reaction mixture was concentrated in vacuo to dryness and the residue triturated with warm tetrahydrofuran and filtered to remove insoluble inorganic material. The filtrate was concentrated in vacuo to give crude 8-(4-amino-benzyl)-1,3-dimethyl-3,7-dihydro-purine-2,6-dione which was of sufficient purity for subsequent use without additional purification (58%).
