Participants

Reaction Steps

7.44 grams of 2-benzyl-2-ethoxycarbonyl-cyclopentanol obtained in Example 14 were diluted with 60 ml of methylene chloride. At room temperature and with magnetic stirring, 3.66 ml of pyridine was slowly added, then 6.12 ml of 4-methyl benzoyl chloride was dropwise added. Upon the completion of the addition, the reaction was continued under reflux condition for 12 hours. Then the procedure as described in Example 23 was followed, to give 12.53 g of yellow liquid. MS: m/e 367(M++1), 366(M+), 364(M+−2), 293(M+—CO2CH2CH3), 247(M+—CH3C6H4CO), 231(M+—CH3C6H4CO2), 201, 184, 156, 139, 119 (base), 91, 77.
