A solution of 1-methoxy-4-(1-hydroxy-1-methylethyl)-1,4-cyclohexadiene in dichloromethane containing 5-(1,2-dimethyl-1-heptenyl)resorcinol was stirred at 0° C. while stannic chloride was added in one portion. The reaction mixture was then stirred for four hours at 24° C., and then washed with hydrochloric acid and water. The solution was dried and the solvent was removed by evaporation under reduced pressure to provide dl-cis-1-hydroxy-3-(1,2-dimethyl-1-heptenyl)-6,6-dimethyl-6,6a,7,8,10,10a-hexahydro-9H-dibenzo[b,d]pyran-9-one.
