Procedure

To a stirred mixture of 5-aminopyrimidine-4-carboxylic acid (200 mg, 1.44 mmol) and 1-amino-2-methylpropan-2-ol (128 mg, 1.44 mmol) at rt in THF (5 ml) under an argon atmosphere were added N-ethyldiisoproplyamine (743 mg, 978 μl, 5.75 mmol) and 1-propanephosphonic acid cyclic anhydride (2.29 g, 2.16 ml, 3.59 mmol). The mixture was stirred at rt for 21 hrs, then concentrated. The crude product was purified by column chromatography with EtOAc/MeOH as eluent providing the title compound (216 mg, 72%) as off-white solid.
