Potassium Carbonate → 3-(1-{[3-(4-methyl-1-piperazinyl)propyl]sulfonyl}-4-piperidinyl)-5-(3-thienyl)-1H-indole-7-carboxamide

Participants

Reaction Steps

Following the general procedure for aminosulfonamide formation outlined in example 2, 3-{1-[(3-chloropropyl)sulfonyl]-4-piperidinyl}-5-(3-thienyl)-1H-indole-7-carboxamide (40 mg, 0.13 mmol) and 1-methylpiperazine (0.068 mL, 0.65 mmol) were allowed to react in the presence of K2CO3 (74 mg, 0.65 mmol). 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 (11.2 mg, 17.2%).
