Participants

Reaction Steps

To a diethyl ether (5 mL) solution of 3-[(methylthio)thiocarbonyl]-2-(4-dimethylamino-1-naphthylimino)-5,5-diisopropyl-1,3-thiazine (I-43: 0.15 g), was added 4N dioxane solution of hydrochloric acid (0.23 mL), and the reaction mixtuer was stirred at room temperature for 0.5 h. The resulting crystals were filterd to obtain 3-[(methylthio)thiocarbonyl]-2-(4-dimethylamino-1-naphthylimino)-5,5-diisopropyl-1,3-thiazine hydrochloric acid salt (I-152: 0.14 g, 94%) as yellow crystals.
