Procedure

To a stirred solution of 15.2 g of 2,2,6-trimethyl-1-oxaspiro(2.5)oct-5-ene in 200 ml of diethyl ether held at -10° C. was added dropwise 32 ml of 3.8N ethereal hydrogen chloride. After one hour at 0°-5° C., the mixture was washed with three 50 ml portions of water, dried and distilled to give 14.5 g of the desired product, b.p. 70°-75° C. (0.4 mm).
