Versuchsvorschrift

2,2-Dimethyl-5-[6-(4-phenoxy-phenoxy)-naphthalen-2-yl]-1,3-dioxinan-5-ylamine (0.1241 g, 0.0002811 mol) was dissolved in methanol (3 mL, 0.07 mol) and a solution of 1 M of hydrogen chloride in water (5 mL, 0.005 mol) in a 40 mL reaction vial equipped with a magnetic stir bar. The vial was capped and heated at 90° C. overnight. TLC analysis showed that the reaction was complete. The reaction mixture was concentrated to dryness under reduced pressure. The resulting solid was dissolved in methylene chloride (5 mL) and washed with water then aqueous sodium carbonate. The combined organic layer was dried over magnesium sulfate, then concentrated under vacuum and purified by HPLC to give 88.3 mg of the title compound (78% yield). MS: m/z=424.45 [M+Na+]. 1H NMR (DMSO-d6) δ: 8.00 (s, 1H), 7.93 (d, J=8.7 Hz, 1H), 7.80 (d, J=8.7 Hz, 1H), 7.62-7.68 (m, 1H), 7.39-7.44 (m, 2H), 7.35-7.39 (m, 2H), 7.30 (dd, J=8.9, 2.5 Hz, 1H), 7.00-7.17 (m, 6H), 3.73 (d, J=3.8 Hz, 4H)
