Versuchsvorschrift

Acetic anhydride (10.4 ml, 0.11 mol) was added to 6-chloro-2-(methylthio)pyrimidin-4-amine (2.5 g, 0.01 mol) and the reaction mixture was refluxed at 135° C. for 5 hr. The reaction mixture was cooled to room temperature and basified to pH 7 with saturated sodium bicarbonate solution (20 ml). The mixture was partitioned between EtOAc and water, the organic layer was washed with water and brine, dried over MgSO4 and concentrated to give the title compound (2.62 g).
