Procedure

30 μl (0.419 mmol) of 1,3-propanediol are initially charged in 2 ml of DMF, 18 mg (0.154 mmol) of potassium tert-butoxide are added and the mixture is stirred for 15 minutes, after which 75 mg (0.14 mmol) of 2-chloro-6-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-4-(1,3-thiazol-5-yl)pyridine-3,5-dicarbonitrile, dissolved in 2 ml of DMF, are added. The reaction mixture is stirred at room temperature for 30 minutes and then purified by preparative HPLC (acetonitrile/water: 10:90→95:5). This gives 11 mg (15% of theory) of the target compound.
