Participants

Reaction Steps

N-[(6-Bromopyridin-2-yl)sulphonyl]acetamide (0.112 g, 0.4 mmol), 3-(1,3-thiazol-2-yl)pyridine (0.065 g, 0.4 mmol, prepared by the methods described in WO 2010/006713), dichloro{bis[di-tert-butyl(hydroxy)phosphoranyl]}palladium (0.006 g, 0.012 mmol) and caesium carbonate (0.26 g, 0.8 mmol) were stirred in 10 ml of N,N-dimethylformamide at 120° C. under argon for 16 h. After cooling, the solvent was removed under reduced pressure and the residue was chromatographed (silica gel, dichloromethane/methanol eluent). This gave 0.024 g (15% of theory) of N-({6-[2-(pyridin-3-yl)-1,3-thiazol-5-yl]pyridin-2-yl}sulphonyl)acetamide.
