Yield	Reaction Conditions	Operation in experiment
95.4%	In methanol; at 65℃; for 2h;Inert atmosphere;	A solution of the compound of formula (VH) (800 mg, 4.73 mmol) was added to 12.5 mL of anhydrous methanol and nitrogen purged. The solution was transferred to a 2.3 M solution of 5.4 M sodium methoxide in methanol. After refluxing at 65 C for 2 h, 7.5 mL of acetic acid was added 5min, the solvent was removed and dried in vacuo to give 745 mg of a tan solid 95.4%.
