Reaction Steps

To a stirred solution of 76 g of 2,2,6-trimethyl-1-oxaspiro(2.5)oct-5-ene in 300 ml of n-pentanol were added 2.0 g of 60% sodium hydride and 60 g of thiophenol. After 18 hours reflux, the mixture was vacuum concentrated at 90°-95° C. The residue was dissolved in methylene chloride and washed twice with 2N sodium hydroxide. The dried solution was Claisen-distilled to give 106 g of crude product, b.p. 120°-125° C. Recrystallization from 250 ml of hexane gave 69.1 g of the desired product, m.p. 73°-74° C.
