Methyl iodide → 1-methyl-8-nitro-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one

Participants

Reaction Steps

144 mg of NaH (50%) are added to a solution of 549 mg of 8-nitro-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in 15 ml of DMF. The reaction medium is stirred for 15 minutes and then 187 μl of iodomethane are added. The mixture is stirred for 16 hours at ambient temperature and then run into ice-cold water and extracted with ethyl acetate. The organic phase is washed with a saturated sodium chloride solution, dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue is taken up in diisopropyl ether and the insoluble material is filtered off and dried under vacuum, so as to give 405 mg of 1-methyl-8-nitro-1,3,4,5-tetrahydro-2H-1-benzazepin-2-one in the form of a beige solid.
