The mixture is subsequently stirred at RT for 45 min, then adjusted to pH 5 with 2 N hydrochloric acid and subsequently stirred at RT for a further 16 h. The mixture is cooled to 10° C. and the solid is filtered off and washed with 3.5 ml dioxane. The mixture is dried under a high vacuum for 16 h, 5 ml methanol are then added and the mixture is subsequently stirred at RT for 1 h. The solid is filtered off, washed with 2 ml methanol and dried under a high vacuum to give a further 997 mg of the title compound in this way.
