Reaction Steps

To a solution of N-[2-chloro-5-(1-hydroxy-1-methyl-ethyl)-phenyl]-3,4-dimethoxy-benzenesulfonamide (0.98 g, 2.5 mmol) in DMF (7.5 mL) was added 2-Chloro-N,N-diethyl-acetamide (0.418 g, 1.1 eq) and K2CO3 (0.35 g, 1 eq). The mixture was heated at 80° C. over night, cooled and partitioned between EA and water. The organic layer was washed several times with water and brine, dried over MgSO4 and concentrated. The residue was purified by chromatography on SiO2 (hex/EA 1:1, EA) to give the product as a colourless foam (1.15 g, 92%).
