Reaction Conditions

Reaction Steps

To 2-amino-4-[[(1-hydroxymethyl-1-cyclobutyl)methyl]amino]pyrimidine (0.21 g, 1.0 mmol) was added acetic acid (3 ml) and the mixture was heated to 110° C. Sodium acetate 3 hydrate (0.18 g) was added and bromine (60 μl) dissolved in acetic acid (0.5 ml) was dropwise added at 70° C. After cooling, water was added to the reaction mixture and the mixture was neutralized with aqueous ammonia under ice-cooling, extracted with ethyl acetate and dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure and the residue was recrystallized from acetone to give colorless prism crystals (0.21 g, 72.4%), m.p. 156-158° C. (acetone).
