実験手順
To a 3-neck 5-L flask equipped with a reflux condenser, a mechanical stirrer and a temperature probe was added 3-acetylamino-adamantane-1-carboxylic acid (432 g, 1.82 mol), water (1.00 L) and concentrated hydrochloric acid (2.44 L), and the resulting mixture was heated at 95° C. for 6 days. During this time, solid material precipitated from the solution. After cooling at 0° C., the solids were filtered and washed with acetone. The solid was then dried under high vacuum at 50° C. for about 2 hours to afford 328 g (78%) of the title compound, 3-amino-adamantane-1-carboxylic acid hydrochloride, as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 12.35 (br s, 1H), 8.27 (br s, 3H), 2.22-2.12 (m, 2H), 1.92-1.85 (m, 2H), 1.83-1.71 (ml 6H), 1.69-1.48 (m, 4H).
