INTERMEDIATE 30; This shows the preparation of 4-[5-(aminosulfonyl)-2-thienyl]thio}benzoic acid.To a solution of 5-bromothiophene-2-sulfonamide (242 mg) and 4-mercaptobenzoic acid (154 mg) in DMF (1 mL) was added aqueous 2 N sodium hydroxide solution (1 mL). The reaction mixture was heated in a CEM Discover microwave at 150C for 25 min. After this time it was allowed to cool, then it was diluted with water (20 mL) and acidified with 10 % v/v aqueous hydrochloric acid. The fine precipitate that formed was difficult to filter so the EPO <DP n="47"/>majority of the liquid was decanted from the solid, and the gelatinous residue concentrated to dryness in vacuo to give the title compound 4-[5-(aminosulfonyl)-2- thienyl]thio}benzoic acid (280mg).1H NMR (300 MHz, DMSO) δ 13.03 (s, 1H), 7.91 (d, 2H), 7.85 (s, 2H), 7.59 (d, 1H), 7.50 (d, 1H), 7.34 (d, 2H).

YieldReaction ConditionsOperation in experiment
With hydrogenchloride; sodium hydroxide; In methanol; N,N-dimethyl-formamide; A solution of 4-mercaptobenzoic acid (5.09 g, 33 mmol) in DMF (60 ml) was added to a slurry of 60percent NaOH (2.64 g, 66 mmol) in DMF (60 ml) under argon at 0° C. This mixture was stirred at 0° C. for 90 minutes prior to the dropwise addition of a solution of 1-(tert.-butyldimethylsilyloxy)-2-iodoethane (8.59 g, 30 mmol) in DMF (30 ml). The resultant reaction mixture was stirred for 3 hours at room temperature, then poured over a mixture of 0.5N HCl (70 ml) and ice (200 g) and diluted with water (500 ml). The precipitate that formed was collected by filtration to give a peach-colored solid (9.28 g, 99percent yield) which was used without further purification. The above product 4-[2[(t-butyldimethylsilyloxy)-ethyl]thio]benzoic acid (8.75 g, 28 mmol) was dissolved in CH3 OH (300 ml) containing conc. H2 SO4 (3 ml) and this solution was refluxed overnight. The solvent was removed by concentration, in vacuo, and the residue was partitioned between saturated NaHCO3 (300 ml) and ether (300 ml). The layers were separated and the aqueous phase extracted with EtOAc (200 ml). The combined organic extracts were dried over Na2 SO4 and concentrated, in vacuo, to give an orange gum which was purified by flash chromatography. Elution with hexane/EtOAc (2:1) yielded the product as a white solid (3.53 g, 59percent yield) which melted at 58° C. The following analyses indicate that that product was methyl 4-(2-hydroxyethyl)thio benzoate: NMR(CDCL3) delta=7.94(2H, d, J=8.5 Hz), 7.36(2H,, d J=8.5 Hz), 3.90(3H, s), 3.83(2H, q, J=6.1 Hz), 3.21 (2H, t, J=6.1 Hz), 1.96(1H, t, J=6.1 Hz)
