Nitrogen gas is bubbled through a solution of 3-amino-3-[4-benzyloxy-7-(4-chloro-phenylsulfanyl)-3-methoxybicyclo[4.2.0]octa-1,3,5-trien-7-yl]-acrylic acid tert-butyl ester (0.6 g, 1.1 mmol) in 1,2-dichlorobenzene (100 mL) for 1 hour and the reaction is heated to 179° C. After one hour the reaction is cooled and reduced in vacuo. The residue is washed with ether, dissolved in methylene chloride and purified through a plug of silica eluting with methylene chloride. The filtrate is reduced and dried to afford 0.321 g of 3-amino-6-benzyloxy-7-methoxynaphthalene-2-carboxylic acid tert-butyl ester as a yellow solid, mp 179–180° C.
