Reaction Steps

0.2 g (0.76 mmol) of methyl 2-cyano-3-[(4-methyl-3-pyridinyl)amino]-3-(methylsulfanyl)-2-propenoate are dissolved with 0.13 g (0.85 mmol) of 2-cyclopentylethanamidine hydrochloride and 0.23 g (1.67 mmol) of potassium carbonate in 4 ml of DMF and stirred at 90° C. for 3 days. After cooling, the product is purified by preparative HPLC (YMC Gel ODS-AQ S 5/15 μm; eluent A: water, eluent B: aceto-nitrile; gradient: 0 min 30% B, 5 min 30% B, 50 min 95% B) purified. 60 mg (25% of theory) of the product are obtained.
