Reaction Conditions

Reaction Steps

37.6 g of lithium aluminum hydride and 800 ml of tetrahydrofuran were added to a flask and maintained at 0° C. in a nitrogen atmosphere. Then, 200 g of 8-methyl-8-methoxycarbonyltetracyclo[4.4.0.12,5.17,10]dodec-3-ene dissolved in 200 ml of tetrahydrofuran was added from a dripping funnel over one hour, followed by a reaction for 2.5 hours at 70° C. The reaction solution was allowed to cool to room temperature and a 10% aqueous solution of potassium hydroxide was added gradually, followed by further addition of 10% aqueous solution of hydrochloric acid. The reaction solution was then extracted with toluene and the reaction product was salted out from saturated brine. The salt-out product was washed several times with water and dried over anhydrous magnesium sulfate. Toluene was evaporated to obtain 145 g of a white solid of 8-methyl-8-hydroxymethyltetracyclo[4.4.0.12,5.17,10]dodec-3-ene shown by the following formula (19).
