Reaction Steps

To a solution of 3,5-dichloro-4-hydroxybenzoic acid (4.0 g, 19.3 mmol) in THF (60 ml) under argon was added borane-THF complex (39.0 mmol, 39.0 ml of 1 M solution in THF) dropwise. After addition, the reaction mixture was heated at 60° C. for 6 h, then quenched with water and extracted with ethyl acetate three times. The organic extract was washed with water, then brine, dried (sodium sulfate) and concentrated in vacuo to afford the title compound (3.7 g, 99%) as white solid. 1H NMR (400 MHz, CDCl3) δ 7.28 (s, 2H), 5.83 (s, 1H), 4.59 (s, 2H), MS: (M+1-H2O)=175
