Procedure

3-{1-[(3-chloropropyl)sulfonyl]-4-piperidinyl}-5-(3-thienyl)-1H-indole-7-carboxamide (60 mg, 0.129 mmol) was reacted with sodium ethoxide (0.5 M in ethanol, 0.5 mL, 0.25 mmol) in a mixture of ethanol (5 ml) and DMSO (0.2 mL) at reflux for 16 h to form the desired product which was purified by reverse phase HPLC eluting with 10% B to 70% B, where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) to give the title compound (10 mg, 17%).
