1,3-Propanediol → 2-({[2-(4-Chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-6-(3-hydroxypropoxy)-4-phenylpyridine-3,5-dicarbonitrile

Participants

Reaction Steps

68 μl (0.939 mmol) of 1,3-propanediol are initially charged in 2 ml of DMF, 38 mg (0.344 mmol) of potassium tert-butoxide are added and the mixture is stirred for 15 minutes, after which 150 mg (0.313 mmol) of 2-chloro-6-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-4-phenylpyridine-3,5-dicarbonitrile, dissolved in 2 ml of DMF, are added. The reaction mixture is stirred at room temperature for 1 hour and then purified by preparative HPLC (acetonitrile/water: 10:90→95:5, with 0.1% TFA added). This gives 98 mg (59% of theory) of the target compound.
