실험 절차

The oxidation of 2-benzylthio-5-bromopyrimidine was carried out using one molar equivalent of 85% m-chloroperbenzoic acid in dichloromethane, initially at -10° C. and then at 0° C., as described in Example 40 above; yield 91%, m.p. 101° C. (iPrOH). 1H NMR (CDCl3); δ4.26 and 4.31 (CH2), 7.16 (Ph), 8.80 (H-4, H-6).
