Cyclopropylamine → 2-({(2-(4-Chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-6-(cyclopropylamino)-4-(4-(2-hydroxyethoxy)phenyl)pyridine-3,5-dicarbonitrile

Participants

Reaction Steps

At RT, 50 mg (0.09 mmol) of 2-chloro-6-({(2-(4-chlorophenyl)-1,3-thiazol-4-yl)methyl}sulfanyl)-4-(4-(2-hydroxyethoxy)phenyl)pyridine-3,5-dicarbonitrile (Example 2A) and 0.013 ml (0.19 mmol) of cyclopropanamine were stirred in 1.3 ml of DMF overnight. The crude product was purified directly by preparative HPLC (acetonitrile/water). The collected product fractions were once more dissolved in 2 ml of DMF, 0.013 ml (0.19 mmol) of cyclopropanamine was added and the mixture was stirred at RT overnight. The crude product was then once more purified by preparative HPLC (acetonitrile/water). This gave 20 mg (39% of theory) of the desired target compound.
