Cyclopentylamine → 3-(1-{[2-(cyclopentylamino)ethyl]sulfonyl}-4-piperidinyl)-5-(2-thienyl)-1H-indole-7-carboxamide

Participants

Reaction Steps

Following the general procedure for aminosulfonamide formation outlined in example 2, 3-{1-[(2-chloroethyl)sulfonyl]-4-piperidinyl}-5-(2-thienyl)-1H-indole-7-carboxamide (0.09 mmol) and cyclopentanamine (0.04 mL, 0.45 mmol) were allowed to react in the presence of K2CO3 (44 mg, 0.45 mmol) and NaI (Cat. 5 mg). The resulting residue was purified by reverse phase HPLC eluting with 10% B to 80% B, where A=H2O (0.1% trifluoroacetic acid) and B=CH3CN (0.1% trifluoroacetic acid) to give the title compound (14 mg, 39%).
