Versuchsvorschrift

To a solution of N-{2-[5-(2-hydroxyethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (200 mg) and triethylamine (70 μL) in tetrahydrofuran (5 mL) was added methanesulfonyl chloride (60 mg) at room temperature, and the mixture was stirred for 3 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4), and concentrated. The obtained residue was subjected to silica gel column chromatography to give 2-(2-{7-[methyl(2-thienylsulfonyl)amino]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)ethyl methanesulfonate (126 mg, yield 54%, MS:500(MH+)) and N-{2-[5-(2-chloroethyl)-4,5-dihydro-1,3-thiazol-2-yl]-1H-indol-7-yl}-N-methylthiophene-2-sulfonamide (16 mg, yield 8%, MS:440(MH+)), as a white amorphous solid from a fraction eluted with ethyl acetate, respectively.
