PROCEDURE

实验过程

0.05 g of the compound obtained in EXAMPLE 1' and 0.04 g of the compound obtained in step A are dissolved in the heated state in 2 ml of 2-propanol, and the mixture is concentrated under vacuum. The residue is dissolved in 0.3 ml of water and 8 drops of dioxane, and crystallization is allowed to take place at RT. The crystallized product formed is drained, washed with water and dried at 90° C. under vacuum. 0.042 g of expected product is obtained, m.p.=266° C. (dec.).
