Reaction Steps
To 7-fluoro-2,2-dimethyl-3,4-dihydro-2H-chromene-4-carboxylic acid (0.280 g, 1.25 mmol) in CH2Cl2 (5 mL) and MeOH (1 mL) was added TMSCHN2 (0.937 mL, 1.87 mmol) dropwise. After the addition, the reaction was concentrated, loaded onto silica gel, and the product eluted using a gradient of 5% ethyl acetate/hexanes to 40% ethyl acetate/hexanes to provide the title compound (0.225 g, 75.6% yield).
