Methyl iodide → HCID 11653881, compound

Participants

Reaction Steps

A solution of 1 of (4-chloro-3-trifluoromethyl-phenyl)-carbamic acid -1,2,3,4-tetrahydro-quinolin-6-yl ester (0.74 g., 2 mmol) in dry dimethylformamide (5 ml) was added to a stirred suspension of sodium hydride (0.048 g., 2 mmol) in dry dimethylformamide (5 ml) at −10° C. during 5 min. The reaction mixture was stirred for 30 min. Then methyl iodide (0.224 ml, 3.6 mmol) was added to the stirring reaction mixture. Stirring was continued for additional 1.25 hours during which the temperature was allowed to rise to room temperature (34° C.). The reaction mixture was quenched with water (0.2 ml), concentrated under vaccum, diluted with water (5 ml), extracted with chloroform (2×5 ml) and dried over sodium sulphate. The combined fractions of chloroform were concentrated under vaccum. The residue was chromatographed on silica gel using dichloromethane-hexane (20:80) as eluant to give 2q; yield: 0.42 g. (54.6%).
