Reaction Steps
To a stirred solution of p-anisidine (74 mg, 0.6 mmol), pyridine (0.14 ml, 1.0 mmol) and 4-dimethylaminopyridine (10 mg) in EtOAc (10 ml) was added a solution of (R)-N-[2,3-dichloro-4-(chlorosulphonyl)phenyl]-3,3,3-trifluoro-2-hydroxy-2-methylpropanamide (200 mg, 0.5 mmol) (Method 1) in EtOAc (10 ml). The resultant mixture was stirred at ambient temperature overnight, washed with 1 M aqueous hydrochloric acid, saturated sodium hydrogen carbonate solution and brine, dried and evaporated. The residue was chromatographed on a Bond Elut column (using 10% EtOAc in DCM as eluent) to give the title compound as a foam (114 mg, 0.23 mmol); NMR: 1.6 (s, 3H), 3.6 (s, 3H), 6.8 (d, 2H), 7.0 (d, 2H), 7.95 (d, 1H), 8.1 (d, 1H); m/z 485.
