Procedure

A solution of 4-methyl-7-[methyl(2-thienylsulfonyl)amino]-1H-indole-2-carboxylic acid (3.0 g), 2-(benzylthio)-3,3-dimethoxypropan-1-amine (2.4 g), N-ethyldiisopropylamine (3.7 mL) and O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (4.2 g) in N,N-dimethylformamide (40 mL) was stirred at room temperature for 8 hr. The reaction solution was diluted with ethyl acetate, washed with water, aqueous sodium hydrogencarbonate solution and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was subjected to silica gel column chromatography (ethyl acetate:hexane=2:3-3:2) to give the title compound (4.75 g, yield: 97%) as a pale-yellow oil. MS: 542 (MH+).
