Procedure
A solution of 4-(2-propylguanidino)-2-methylthiopyrimidine (1.6 g.) in MeOH (25 ml.) was heated on a steam bath while a solution of sodium metaperiodate (1.6 g.) in water (15 ml.) was added dropwise over 15 minutes. Further sodium metaperiodate in water (10% w/v) was added until analysis by t.l.c. on silica using EtOAc/MeOH 4:1 v/v as eluant showed absence of starting material. The reaction mixture was evaporated in vacuo, and the residue partitioned between methylene chloride and water. The organic phase was worked up to give 4-(2-propylguanidino)-2-methylsulphinylpyrimidine, m.p. 179°-180°.
