Procedure
Methyl 7-(4-((1,2,3,4-tetrahydronaphthalen-2-yl)carbamoyl)phenoxy)-6-cyanochroman-4-carboxylate (10 mg, 0.021 mmol) was diluted with THF (500 μL) followed by the addition of NaOH (0.12 ml, 0.12 mmol) and methanol (100 μL). After stirring for 1 hour, the reaction was diluted with ethyl acetate and 2N HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated to yield 7-(4-((1,2,3,4-tetrahydronaphthalen-2-yl)carbamoyl)phenoxy)-6-cyanochroman-4-carboxylic acid (3.0 mg, 31% yield). MS (ESI)=469.0 (M+H).
