実験手順

A mixture of 1 g methyl 1-acetylamino-2-chloro-5a,6,7,8,9,9a-hexahydrodibenzofuran-4-carboxylate and 1 g of dichlorodicyanoquinone in 15 ml of benzene is stirred and heated at 80° C. in a sealed tube for 8 hours. The coooled reaction mixture is then diluted with benzene, filtered and evaporated to dryness. Purification by recrystallization from ethyl acetate/hexane gives pure methyl 1-acetylamino-2-chloro-6,7,8,9-tetrahydrodibenzofuran-4-carboxylate.
