실험 절차

To a mixture of 150 ml of concentrated sulfuric acid and 15 ml of concentrated nitric acid, cooled to 10° C. is added 10 g (0.053 moles) of 1-adamantanamine hydrochloride over 5 minutes. This mixture is stirred in an ice bath for 4 hours. The reaction is then poured over ice and the pH adjusted to pH 10 using 50% NaOH. The product is extracted into chloroform which is dried over MgSO4 and then evaporated to dryness. The residue is recrystallized from ethyl acetate to give 3-hydroxytricyclo[3.3.1.13,7 ]decan-1-amine (m.p. 260°-264° C.) which is used directly in step B.
