실험 절차

A mixture of 256 grams (0.62 mol.) of 1,2,3,4,6,9,9-heptachloro-1,4,4a,8a-tetrahydro-1,4-methanonaphthalene-5,8-dione, prepared according to Example 24, and 500 ml. of methanol in a 2 liter reaction flask was stirred at room temperature while air in the reaction vessel was swept out with nitrogen. Six ml. of pyridine was then added to the liquid-solid mixture. The resulting reaction mixture was continuously stirred, and refluxed vigorously for 8.5 hours. After cooling the mixture to 0° C., it was filtered, and the crude solid was washed with cold Skellysolve. Yield 121 grams. The product was recrystallized from a mixture of 1000 ml. of Skellysolve and 250 ml. of acetone. M.P. 120.5°-122° C. The product has the following structure: ##STR57##
