Methyl iodide → HCID 60161544, compound

Participants

Reaction Steps

A solution of 1,2,3,4-tetrahydroquinolin-7-yl 2-fluorophenylcarbamate (300 mg, 1.84 mM) in dry dimethylformamide (DMF, 5 mL) was added to the stirred solution of sodium hydride in dry DMF at −10° C. during 5 minutes under nitrogen environment. The reaction mixture was stirred for 30 minutes. Then, methyl iodide (285 mg/ml, 2 mM), was added to the stirring reaction mixture. The mixture was stirred further for 3 hours during which the temperature was allowed to reach the room temperature (37° C.). The reaction mixture was quenched with water, diluted with water, extracted with ethyl acetate 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 the pure compound 8l as oil. Yield: 300 mg, 54.33%.
