실험 절차

Methyl 7-(4-((4-chlorophenethyl)carbamoyl)phenoxy)-6-cyanochroman-4-carboxylate (100 mg, 0.204 mmol) was diluted with THF (1 mL) followed by the addition of NaOH (0.204 mL, 1.02 mmol) and 500 μL of water and methanol. After stirring for 3 hours, 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. The material was purified using the Horizon with a 25 cartridge and running a gradient 0.5% methanol/0.5% acetic acid/CH2Cl2 to 10% methanol/0.5% acetic acid/CH2Cl2 to yield the title compound (21 mg, 21.6% yield) as a white solid. MS (ESI)=476.9 (M+1).
