Sodium Methoxide → 4-Chloro-6-methoxy-2-(methylthio)-5-nitropyrimidine

Participants

Reaction Steps

A mixture of 4,6-Dichloro-2-methylthio-5-nitropyrimidine (5.25 g, 21.88 mmol) in methanol (40 mL) was treated with sodium methoxide (1.3 g, 24.06 mmol). The mixture was stirred at room temperature for 3 h. At this point the reaction was poured onto ice to give a brown solid which was filtered and washed with water. The solid was dried under vacuo to give 4-Chloro-6-methoxy-2-methylthio-5-nitropyrimidine (4.40 g, 85%) as a brown solid. LRMS for C6H6Cl1N3O3S (M+H)+ at m/z=235. The NMR spectrum obtained on the sample is compatible with its structure.
