実験手順

100 mg (0.620 mmol) of the compound from example 3A, 100 mg (0.310 mmol, 50% purity) of the compound from example 5A and 51 mg (0.620 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). 78 mg (66% of theory) of the title compound are obtained.
