Reaction Steps

Add oxalyl chloride (0.660 mg, 5.20 mmol) to a solution of 3-[[4-(3-hydroxy-2-methyl-4-propionyl-phenoxymethyl)-phenyl]-(tetrahydro-pyran-2-yloxy)-methyl]-benzoic acid (2.50 g, 5.00 mmol) in tetrahydrofuran (0.20M). Add dimethylformamide (5 drops). Add ethereal solution of diazomethane (15.0 mmol) and stir for 2 hours. Add hydrochloric acid (4N in dioxane) to quench unreacted diazomethane and evaporate solvents to afford the title compound (2.25 g, 4.19 mmol, 85%): MS (m/z): 536 (M−H).
