실험 절차

150 mg (0.876 mmol) of the compound from example 23A, 135 mg (0.876 mmol) of the compound from example 4A and 71 mg (0.876 mmol) of 3-aminocrotononitrile are dissolved in 4 ml of isopropanol and stirred at the reflux temperature overnight. After cooling to room temperature, the volatile components are removed in a rotary evaporator, and the crude product is purified by preparative HPLC (eluent: acetonitrile/water with 0.1% formic acid, gradient 20:80→95:5). 145 mg (44% of theory) of the title compound are obtained.
