Sodium borohydride → 6-(Hydroxymethyl)-3-methyl-1-(2-methylpropyl)-5-(2-thienylmethyl)-thieno[2,3-d]pyrimidine-2,4(1h,3h)-dione

Participants

Reaction Steps

Sodium borohydride (0.06 g) was added to 1,2,3,4-tetrahydro-3-methyl-1-(2-methylpropyl)-2,4-dioxo-5-(2-thienylthio)-thieno[2,3-d]pyrimidine-6-carboxaldehyde (0.25 g) in methanol (25 ml) and the mixture was stirred for 24 hours. The reaction was diluted with water (30 ml) and was then extracted with ethyl acetate (3×50 ml). The organic phases were washed with brine and dried over magnesium sulfate, filtered and evaporated to leave a green oil. Purification by chromatography (1:4 ethyl acetate:isohexane) gave the subtitle compound as a yellow foam (0.125 g).
