実験手順
The acid from Step 1 (0.84 g) was dissolved in 10 mL of Et2O and a solution of diazomethane in Et2O was added portionwise until all the acid had been consumed. Excess diazomethane was removed by addition of 1 mL HOAc, the solvent was then removed and the residue chromatographed (hexane/EtOAc 4:1) to give the title compound.
