Procedure

To a solution of N-methyl-N-[2-(1-thia-3,8-diazaspiro[4.5]dec-2-en-2-yl)-1H-indol-7-yl]thiophene-2-sulfonamide (100 mg) and 1-methyl-1H-imidazole-2-carbaldehyde (33 mg) in tetrahydrofuran (3 mL) was added sodium triacetoxyborohydride (125 mg), and the mixture was stirred at room temperature for 18 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 the title compound (14 mg, yield 12%) as white crystals from a fraction eluted with ethyl acetate. melting point 103° C.
