Procedure

A suspension of methyl 2-chloro-6-(4-{[(3,4-dichloro-5-methyl-1H-pyrrol-2-yl)carbonyl]amino}piperidin-1-yl)pyrimidine-4-carboxylate (Example 6, 150 mg, 0.34 mmol), 2-mercaptoethanol (31 mg, 0.40 mmol) and potassium carbonate (139 mg, 1.01 mmol) in DMF (3 ml) were stirred at 65° C. under nitrogen for 3 hours. The mixture was cooled to room temperature and diluted with EtOAc (75 ml) and 1 N HCl (3 ml). The organic layer was separated, dried over Na2SO4, filtered and concentrated under vacuum. Purification of the residue by reversed-phase HPLC (water/acetonitrile gradient, 10-95%) gave 39 mg of the title compound.
