Procedure

9.0 g (28 mmol) N-(8-phenyl-4,5-dihydro-thiazolo[4,5-h]quinazolin-2-yl)-acetamide (prepared analogously to Example 64) are refluxed for 2 hours in 130 ml semi-concentrated hydrochloric acid. After cooling the reaction mixture is made basic, the precipitate formed is suction filtered and dried. Yield: 7.3 g
