Procedure

To a solution of methyl 5-(1-aminoethyl)thiophene-2-carboxylate hydrochloride (33.2 mg, 0.150 mmol) and N,N-diisopropylethylamine (104 μL, 0.60 mmol) dissolved in 1,2-dichloroethane (1 mL) was added isocyanatocyclopentane (24 mg, 0.22 mmol). The reaction solution was shaken at room temperature overnight. The solution was further diluted with DCE (2 mL) and washed with saturated aqueous NaHCO3 (2 mL). The layers were separated and the organic layer concentrated to afford methyl 5-(1-(3-cyclopentylureido)ethyl)thiophene-2-carboxylate as an oil residue. LC-MS: (FA) ES+ 297.
