Procedure
Methyl 7-(4-((2,3-dihydro-1H-inden-2-yl)carbamoyl)phenoxy)-6-cyano-3,4-dihydro-2H-chromene-4-carboxylate (12 mg, 0.026 mmol) was diluted with THF (500 μL) followed by the addition of NaOH (1.0 mg, 0.026 mmol), water (200 μL) and methanol (200 μL). After stirring for 2 hours, the reaction was diluted with 2N HCl and ethyl acetate. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated to yield the title compound (10 mg, 86% yield). 1H NMR (400 MHz, CD3OD) δ 7.90 (d, 2H), 7.64 (s, 1H), 7.15-7.22 (m, 4H), 7.15 (d, 2H), 6.41 (s, 1H) 4.20-4.35 (m, 3H), 3.82 (bt, 1H), 3.3-3.4 (m, 2H), 2.95-3.05 (m, 2H), 2.35-2.40 (m, 1H), 2.10-2.15 (m, 1H).
