(Diethylamino)sulfur trifluoride → HCID 15006821, compound

Participants

Reaction Steps

A solution of 0.7 ml of diethylaminosulfurtrifluoride (DAST) in 10 ml of dichloromethane is added in the course of 10 minutes, at 0° C., to a suspension of 2.1 g of 5-octyloxy-2-(4-octyloxyphenyl)pyrimidin-4-one (prepared, for example, in accordance with Boller et al., Z. Naturf. 33b, 433 (1978)) in 30 ml of dichloromethane. After 8 h at 40° C., aqueous sodium bicarbonate solution is added. After chromatography and recrystallization from acetonitrile, the organic phase yields 0.7 g of colorless crystals.
