실험 절차

A solution of hydrogen chloride in dioxane (4M, 1.6 ml) was added at 20° C. to a stirred solution of Intermediate 146 (140 mg, 0.6 mmol), in dioxane (1.6 ml). After 3 h, the reaction mixture was concentrated in vacuo to afford Intermediate 147 (96.5 mg) containing 4-fluoro-3-cyclohexen-1-amine. 1H NMR (400 MHz in d6-DMSO, 27° C., δ ppm) Minor component: δ8.22 (br, 3H excess), 5.18 (dm, 16 Hz, 1H), 3.28-3.13 (m, 1H excess), 2.41-1.53 (m's, 6H excess). Major component: δ8.22 (br, 3H excess), 3.28-3.13 (m, 1H excess), 2.41-1.53 (m's, 8H excess). Impurities are also present.
