Reaction Conditions

Reaction Steps

A mixture of 4-amino-5-carboxy-2-ethylmercaptopyrimidine (0.35 g, 1.8 mmol) and morpholine (0.5 mL, 10 mmol) was warmed at 80° C. for 4 d and concentrated in vacuo. The residue was purified by flash chromatography (silica gel, 4×7.5 cm, eluted with 97.25/2.5/0.25 acetonitrile/water/acetic acid) to yield the product as a white solid (34 mg, 30%).
