Reaction Steps

26.1 g (258 mmol) of diisopropylamine are added with stirring to a solution of 29.9 g (86 mmol) of the product from Example 17 in 100 ml of toluene. The mixture is heated to reflux and kept at this temperature for 24 hours. After cooling, a solution of 4.1 g of NaOH in 21 ml of water is added. The solid product is filtered off and recrystallized from 25 ml of toluene. A yellowish powder which melts at 179°-184° is obtained.
