Reaction Steps

To a stirring solution of 5-(4-(difluoromethoxy)-2-hydroxy-3-methoxyphenyl)isobenzofuran-1(3H)-one (100 mg, 0.31 mmol) in acetonitrile (10 mL) was added potassium carbonate (128 mg, 0.930 mmol) and 3-bromo-2,2-dimethyl-propan-1-ol (155 mg, 0.930 mmol) and the resultant reaction mixture was heated to 80° C. for 16 h. The reaction mixture was cooled to RT, filtered through celite and the filtrate was concentrated under reduced pressure. The residue was purified by prep TLC to afford title compound as a solid (10 mg, 8%).
