m-Chloroperbenzoic acid → HCID 86745362, compound

Participants

Reaction Steps

7.2 g of m-chloroperbenzoic acid (about 50% pure) are added to a solution of 10.2 g of methyl 2-[2-(2-phenylethenyl)phenyl]-3-methoxyacrylate in 80 ml of methylene chloride. The reaction mixture is refluxed for two days and then the precipitate is filtered off with suction and the filtrate is washed twice with saturated sodium bicarbonate solution and water. The isolated organic phase is dried over sodium sulfate and concentrated, and the residue is recrystallized from methyl tert-butyl ether. 6.2 g (58%) of methyl trans-2-[2-(3-phenyl-2-oxiranyl)phenyl]-3-methoxyacrylate are obtained of melting point 110°-113° C.
