Procedure

A solution of 11 grams of norbornene diol prepared as in Example 2 in 100 ml pyridine was cooled by dry ice. 45 ml of acetic anhydride was added to the cooled solution. The solution was held in the dry ice bath for about 30 minutes then allowed to sit at room temperature for about 16 hours, poured into an ice water slurry, extracted with chloroform and washed sequentially with 10% HCl, a saturated sodium bicarbonate solution, a sodium chloride solution, twice with water, then dried over sodium sulfate, and crystallized from a mixture of toluene and hexane to produce about 10 grams of norbornene diacetate.
