Versuchsvorschrift
Compound 1-B (1.45 g, 5.81 mmol) was added to a solution of HCl in dioxane (4 N, 20 mL), and the mixture was stirred at rt until all the starting material was consumed. The mixture was diluted with diethyl ether, the product collected by filtration, and washed with diethyl ether, to afford compound 1-C as an off-white solid (0.89 g, 83%). 1H-NMR (DMSO-d6): δ 6.43 (s, 1H), 6.8-7.2 (br s, 3H) superimposed on 7.05 (m, 1H) and 7.20 (m, 1H), 7.45 (d, 1H), 7.66 (d, 1H); MS: m/z 150.1 (MH+).
