Reaction Steps

This compound was prepared in a fashion analogous to the procedure described in Example 3. Thus, 3-(4-piperidinyl)-5-(2-thienyl)-1H-indazole-7-carboxamide hydrochloride (Intermediate 17) (0.117 mmol) was reacted with ethane sulfonyl chloride (0.02 mL, 0.234 mmol) in the presence of triethylamine (0.04 mL, 0.468 mmol) in methylene chloride (10 mL) to give the title compound (4.9 mg, 10% for the last two steps)
