Reaction Steps

tert-Butyl bromoacetate (0.10 ml, 0.65 mmol, 1.3 equiv) was added to a mixture of NaOt-Bu (60 mg, 1.2 equiv) and 6-chloro-1-hydroxy-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester (150 mg, 0.5 mmol) in DMF (6 ml) and stirred at 60° C. for 2.5 hr then at RT for 3 days. Water was added and the mixture was extracted with EtOAc. After removal of solvent, purification by column chromatography gave 140 mg (68%) of 1-tert-butoxycarbonylmethoxy-6-chloro-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester as orange solids.
