Reaction Conditions

Reaction Steps

A 100 mL round bottom flask was equipped with a magnetic stir bar and charged with a solution of 1.188 g (5.02 mmol) of the product from Step A (the combined product of two experiments) dissolved in 20 mL of methanol was stirred and cooled to 0° C. with an external ice-water bath. A solution of diazomethane in diethyl ether was added slowly until the reaction mixture developed the persistent yellow color and TLC analysis (25% ethyl acetate-hexanes) indicated that esterification was complete. Excess diazomethane was quenched by dropwise addition of acetic acid, and volatiles were removed in vacuo. The residual clear oil was used directly in the next step without further purification.
