Conditions

Temperature
80 °C

Procedure

Add 47 mg (0.89 mmol) acrylonitrile and 57 mg (0.83 mmol) sodium ethylate to 300 mg (0.80 mmol) of the compound from Stage 1. Stir the mixture overnight at 80° C. After cooling, take up the mixture in DMSO and purify directly by RP-HPLC (column: Gromsil 250 mm×30 mm, 10 μm; acetonitrile/water gradient: 0-3 min 5% acetonitrile, 3-50 min 5%→98% acetonitrile, 50-55 min 98% acetonitrile). 160 mg (47% of theor.) of the title compound is obtained as a yellow oil.
