Procedure

Thionyl chloride (800 μL, 10 mmol) was added dropwise to a solution of 5-[3-chloro-2-cyano-5-(1-hydroxyethyl)-6-methoxyphenyl]N,N-dimethylpyridine-2-carboxamide (2 g, 6 mmol), methylene chloride (100 mL) and N,N-dimethylformamide (100 μL) at room temperature. The reaction was stirred for 5 hrs and was complete by LC/MS. The reaction mixture was partitioned between EtOAc and water. The combined organic layer was washed with saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated to give crude 5-[3-chloro-5-(1-chloroethyl)-2-cyano-6-methoxyphenyl]-N,N-dimethylpyridine-2-carboxamide as an oil (1.8 g, 80%). LCMS calculated for C18H18Cl2N3O2(M+H)+: m/z=378.1; found: 378.1.
