Participants

Reaction Steps

Potassium peroxymonosulfate (0.163 g) was added to a stirred suspension of methyl 4-[(1,2,3,4-tetrahydro-3-methyl-1-(2-methylpropyl)-6-(1-naphthalenylmethyl)-2,4-dioxothieno[2,3-d]pyrimidin-5-yl)thio]butanoate (0.246 g) in methanol (3 ml), tetrahydrofuran (3 ml) and water (3 ml). After 1 hour, the reaction mixture was poured into saturated aqueous sodium bicarbonate solution (20 ml) and extracted with ethyl acetate (2×20 ml) The organic extracts were dried over anhydrous magnesium sulfate, filtered and evaporated under reduced pressure. The residue was purified by column chromatography eluting with hexane:ethyl acetate (1:1) followed by trituration with ethyl acetate/hexane to give the title compound (0.80 g)
