1-Ethyl-3-(3'-dimethylaminopropyl)carbodiimide → N-(3-cyano-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)-2,2-diphenylacetamide

Participants

Reaction Steps

EDCI (59 mg; 0.308 mmol) was added to a solution of 2-Amino-3-cyano-5,6-dihydro-4H-cyclopenta[b]thiophene (25 mg; 0.152 mmol) and 2,3-diphenylpropionic acid (70 mg; 0.309 mmol). After stirring for 19 h, the reaction mixture was applied directly to a silica gel column (Merck Silica gel 60; eluent: 10%–33% ethyl acetate/hexanes) to provide 13.0 mg (23%) of N-(3-Cyano-5,6-dihydro-4H-cyclopenta[b]thiophen-2-yl)-2,2-diphenyl-acetamide as a white solid. EI-HRMS m/e calcd for C22H18N2OS (M+H+) 358.1140, found 358.1140.
