Procedure

2-Benzenesulfonylamino-5,6,7,8-tetrahydronaphthalene-1-carboxylic acid methyl ester (Intermediate 4, 0.68 g) was dissolved in dioxane (12 mL) and a solution of lithium hydroxide monohydrate (0.6 g) in water (6 mL) was added. The mixture was heated by microwave irradiation at 160° C. for 15 minutes then diluted with 1N hydrochloric acid. The product was extracted into DCM and the organic solution was separated, dried with magnesium sulfate, filtered and the filtrate was concentrated under vacuum to give the title compound as a white powder.
