Reaktionsschritte

A solution of 2,6-dichloro-5-methoxy-4-vinyl pyrimidine (6.64 g, 32.5 mmol, prepared by Example 2), in methanol:dichloromethane (1:4, 300 mL), was cooled to −78° C. in a dry ice/acetone bath. Ozone was bubbled into the reaction until the starting material was no longer present according to thin layer chromatography (TLC). Dimethyl sulfide (6 mL) was added. The mixture was concentrated on a rotary evaporator at 0° C. to remove the dichloromethane. This provided an unpurified material comprising the title compound. The title compound was not isolated from the unpurified material.
