Reaction Conditions

Reaction Steps

A mixture of 1-(prop-2-ynyl)-1,2,3,4-tetrahydroquinolin-7-ol (400 mg, 2.14 mM) and triethylamine (0.6 mL) in dry tetrahydrofuran (THF; 5 mL) was stirred for half an hour under nitrogen atmosphere at room temperature (35° C.). To the stirred reaction mixture, 4-chlorophenyl isocyanate (411 mg/ml, 3.21 mM) was added at once and then the reaction mixture was further stirred for 32 hours under N2 atmosphere at RT (35° C.). The reaction mixture was concentrated under vacuum and then was added distilled water (15 mL) followed by the extraction with ether (3×15 mL). The ether layer was dried over sodium sulphate and concentrated under vacuum to afford the crude product, which was finally chromatographed using chlorophorm-hexane (1:19) to afford 10f as solid. Yield: 520 mg, 71.42%.
