Reaction Steps

A mixture of 5.0 g (0.036 mole) of 2-mercaptobenzyl alcohol, 6.4 g (0.032 mole) of 1, 3.6 g (0.036 mole) of triethylamine and 25 mL of 2-methoxyethyl ether was held at reflux for 7 h. Additional 1.1 g of mercaptobenzyl alcohol and 0.72 g of triethylamine was added to the reaction mixture and the mixture was held at reflux for additional 16 h. The reaction mixture was cooled and poured into 6N HCl and extracted with methylene chloride. The methylene chloride extract was wasted twice with 10% NaOH, dried over MgSO4 and concentrated in vacto to give 9.6 g of residue. Purification by HPLC (20% EtOAc-hexane) gave 3.7 g (41%) of 16 as an oil.
