Novel synthesis of 1-(1,2,3,5,6,7-hexahydro-s-indacen-4-yl)-3-[4-(1-hydroxy-1-methyl-ethyl) furan-2-sulfonyl]urea, An anti-inflammatory agent

A novel synthesis of the anti-inflammatory agent 1-(1,2,3,5,6,7-hexahydro-s-indacen-4-yl)-3-[4-(1-hydroxy-1-methyl-ethyl)- furan-2-sulfonyl]urea 1 is described. Sulfonamide 5 was prepared starting from ethyl 3-furoate 2. Key steps were a one-pot sulfonylation with chlorosulfonic acid in methylene chloride followed by pyridinium salt formation and reaction with phosphorus pentachloride to provide ethyl 2-(chlorosulfonyl)-4-furoate 7. This sulfonyl chloride was treated with ammonium bicarbonate to form sulfonamide 8, followed by treatment with excess methyl magnesium chloride to provide 4-(1-hydroxy-1-methyl-ethyl)-furan-2-sulfonamide 5. 4-Isocyanato-1,2,3,5,6,7-hexahydro-s-indacene 16 was prepared from indan in five steps. The formation of the desired sulfonyl urea was carried out both with the isolated isocyanate 16 and via an in situ method.

Chemoselective Removal of Dimeric 1,3-Diol Impurities Generated from Methyl Grignard Addition onto Esters

In two separate cases, we have found that 1,3-diol dimeric impurities were common byproducts generated from the methyl Grignard addition onto esters to form the corresponding tertiary alcohols. These impurities proved difficult to purge by recrystallization as they tended to cocrystallize with the desired product. To avoid the necessity of chromatography, we developed a practical procedure for the chemoselective removal of these 1,3-diol impurities from crude tertiary alcohol by simply performing the recrystallization in the presence of phenylboronic acid. This straightforward method proved equally successful for two cases studied, and the procedure was later demonstrated on a multikilogram scale.
