Reaction Steps

To 50 mL acetone plus 1.80 g (4.2 mmol) of 3-[[(1,1-dimethylethyl)amino]sulfonyl]-1-[2-(tetrahydro-2-pyranyloxy)ethyl]1H-indole-2-carboxylic acid was added 4.2 mL 1N HCl and the mixture was stirred overnight. Acetone was then evaporated and the residue extracted with ethyl acetate three times. The organic layer was washed once with brine, dried (Na2SO4) and stripped to dryness. The residue was then taken up in trifluoroacetic acid (20 mL) then evaporated in vacuo after several hours at room temperature. The residue was triturated and collected with ethyl ether to afford 1.37 g of the title compound, m.p. 145°-146° C. dec.
