Procedure

To a solution of 3-(4-((5-chloro-2,2-dimethyl-3-oxo-2,3-dihydrobenzofuran-7-yl)methoxy)-3-fluorophenyl)-2-methylpropanoic acid (106) (80 mg, 0.197 mmol) in tetrahydrofuran/methanol (2:1, 2 mL) was added sodium borohydride (15 mg, 0.393 mmol). After the reaction was stirred at room temperature for 1.5 hours water was added and the solution was extracted with ethyl acetate, dried over sodium sulfate and filtered. The filtrate was concentrated in vacuo to yield 3-(4-((5-chloro-3-hydroxy-2,2-dimethyl-2,3-dihydrobenzofuran-7-yl)methoxy)-3-fluorophenyl)-2-methylpropanoic acid (109). 1H NMR (400 MHz, CDCl3) δ 7.40 (s, 1H), 7.31 (s, 1H), 6.92 (m, 2H), 6.82 (d, J=12.0 Hz, 1H), 5.04 (s, 2H), 4.75 (s, 1H), 2.93 (m, 1H), 2.71 (m, 1H), 2.64 (m, 1H), 1.49 (s, 3H), 1.34 (s, 3H), 1.18 (d, J=6.9 Hz, 3H). LC-MS ESI m/z: found 407.3 [M−H]−.
