実験手順
0.70 g (2 mmol) of the product of Example 15 was dissolved in benzene dehydrated over calcium hydride, 0.3 ml (5 mmol) of methyl isocyanate was added and the reaction mixture was stirred at 50° C. for 4 hours. The crystals formed after coling were filtered, washed with 3×3 ml of benzene, then triturated with 20 ml of hot benzene. The hot mixture was filtered, the precipitate was washed with 3×3 ml of benzene and dried to give 0.65 g (79.6%) of the aimed product, m.p.: 68°-170° C.(decomp.).
