10% Pd/C (0.010 g) was added to a stirred solution of 2-amino-6-methoxypyrimidine-4-carbonitrile (0.107 g, 0.71 mmol, 1 eq) in 4 ml HOAc. A H2 balloon (20 psi) was added. After 2 h the mixture was filtered through Celite. The filter cake was rinsed with MeOH. The organics were combined and the solvent was removed in vacuo. 1 N NaOH was added to pH>8 and the solvent was removed in vacuo. The residue was stirred in EtOAc (30 ml) and saturated aqueous NaHCO3 (1 ml). After 30 min Na2SO4 was added and the mixture was stirred for 10 min. The inorganics were filtered off, and the solvent was removed in vacuo yielding 0.1044 g (0.68 mmol, 95% yield) of the product.
