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

Participants

Reaction Steps

At RT, 150 mg (0.20 mmol, purity about 74%) 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), 64 mg (0.41 mmol) of 3,3-difluoropiperidine hydrochloride and 57 μl (0.41 mmol) of triethylamine were stirred in 3 ml of THF for 2 h. The reaction mixture was then diluted with about 1 ml of water and about 3 ml of THF and purified by preparative HPLC (acetonitrile/water+0.1% TFA). This gave 90 mg (71% of theory) of the target compound.
