Triethylamine → HCID 178471809, compound

Participants

Reaction Steps

A mixture of Trans-(4-Amino-cyclohexyl)-acetic acid ethyl ester hydrochloride (3.63 g, 17 mmol) is solved in dichloromethane (115 mL) and quinoline-4-carbonyl chloride hydrochloride is added (4.184 g, 18 mmol) followed by the slow addition of triethylamine (11.3 mL, 81 mmol) at 0° C. The mixture is stirred at room temperature overnight and the salts obtained are removed by filtration and the filtrate is extracted. The organic layer is washed with NaHCO3 and brine. The organic phases are dried and concentrated to obtain 3.8 g of a crude. After a flash chromatography with heptane/AcOEt 4:1 to AcOEt a solid was obtained that was recrystallized with EtOAc and n-heptane to obtain the title compound as a pink solid (2.72 g, 42% yield). MS (m/e): 341.3 (M+H+).
