1,2-Dichlorobenzene → 2-(p-Methoxybenzoyl)-3-methyl-4-hydroxy-5-allylbenzofuran

Participants

Reaction Steps

A solution of 2-(p-methoxybenzoyl)-3-methyl-4-allyloxybenzofuran (0.7 gm; 2.2 mmoles) in orthodichlorobenzene (3 mL) was refluxed under nitrogen for a period of 4 hours. The mixture was cooled to rom temperature and purified by chromatography on silica gel using 15% ethylacetate in hexane as eluent to yield 650 mg (93%) of 2-(p-methoxybenzoyl)-3-methyl-4-hydroxy-5-allylbenzofuran, mp. 48°-50° C.
