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 (82 mg) and methanesulfonyl chloride (100 μL) in tetrahydrofuran (3 mL) was added triethylamine (100 μL), and the mixture was stirred at room temperature for 30 min. The reaction mixture was concentrated, and water was added. The precipitated crystals were collected by filtration, and washed with water. The obtained crystals were recrystallized from tetrahydrofuran to give the title compound (42 mg, yield 36%) as white crystals. melting point 251° C.
