Reaction Steps

To a stirred solution of ethyl 2-(3-bromo-5-(N,N-dimethylsulfamoyl)-4-hydroxyphenyl)-4-methylpentanoate (0.75 g, 1.77 mmol) in DMSO (25 mL) were added K2CO3 (367 mg, 2.106 mmol) and cyclopropylmethylbromide (0.2 mL, 2.13 mmol) at RT under inert atmosphere. The reaction mixture was stirred at 80° C. temperature over a period of 14 h. After completion of starting material (by TLC), the reaction mixture was cooled to RT and quenched with water and extracted with EtOAc (3×100 mL). Combined organic layers were washed with water (3×75 mL), brine and dried over Na2SO4. After filtration and evaporation, the crude material was purified by column chromatography to afford ethyl 2-(3-bromo-4-(cyclopropylmethoxy)-5-(N,N-dimethylsulfamoyl)phenyl)-4-methylpentanoate (350 mg) as a liquid.
