Dimethylcarbamoyl Chloride → HCID 60161671, compound

Participants

Reaction Steps

A solution of 1-(prop-2-ynyl)-1,2,3,4-tetrahydroquinolin-7-ol (400 mg, 2.14 mM) in dry tetrahydrofuran (THF; 5 mL) was added to the stirred solution of sodium hydride in dry THF at −10° C. during 5 minutes under nitrogen environment at room temperature (25° C.). The reaction mixture was stirred for 30 minutes. Then, N,N-dimethyl carbamoyl chloride (0.25 mL) was added to the stirring reaction mixture. The mixture was stirred further for 7 hours during which the temperature was allowed to reach the room temperature (35° C.). The reaction mixture was diluted with ethyl acetate, washed with water, and dried over sodium sulphate. The combined fractions of ethyl acetate were concentrated under vacuum and chromatographed using ethyl acetate:hexane (1:49) to afford 10g as solid. Yield: 414 mg, 75.6%.
