Reaction Steps

3-{1-[(2-chloroethyl)sulfonyl]-4-piperidinyl}-5-(3-thienyl)-1H-indole-7-carboxamide was prepared according to the procedure for intermediate 11. 3-(4-piperidinyl)-5-(3-thienyl)-1H-indole-7-carboxamide (30 mg, 0.09 mmol) was reacted with triethyl amine (0.025 mL, 0.18 mmol) and 2-chloroethylsulfonyl chloride (0.012 mL, 1.08 mmol) to give 3-{1-[(2-chloroethyl)sulfonyl]-4-piperidinyl}-5-(3-thienyl)-1H-indole-7-carboxamide, which was used in the next step without further purification.
