Reaction Conditions

Reaction Steps

To a stirring solution of 1-bromo-4-(difluoromethoxy)-3-methoxy-2-(methoxymethoxy)benzene (1 g, 3.19 mmol) in methanol (15 mL) was added concentrated hydrochloride (2 mL) and the reaction mixture was heated to 50° C. for 1 h. The reaction mixture was cooled to RT, concentrated under reduced pressure and the obtained residue was basified with sodium bicarbonate solution and extracted with dichloromethane (3×). The combined dichloromethane layers were washed with brine, dried over sodium sulphate and concentrated under reduced pressure to afford the title compound as a solid (800 mg, 93%).
