Methyl iodide → HCID 9903958, compound

Participants

Reaction Steps

A solution of 0.81 g (3 mmol) of 3-fluoro-5-(N-ethylsulfonylamino)-6,7,8,9-tetrahydro-5H-benzocyclohepte (Example 1) in 10 ml of DMA was added dropwise under argon to a suspension of 0.12 g (4.1 mmol) of 80 percent sodium hydride in 5 ml of DMA. After stirring at RT for 3 h, 0.63 g (4.5 mmol) of methyliodide was added dropwise and the mixture was stirred overnight at RT. After distilling off the solvent, the residue was treated with water and extracted with EA. The organic phase was concentrated in vacuo after drying over sodium sulfate. 0.64 g of 3-fluoro-5-(N-ethylsulfonyl-N-methylamino)-6,7,8,9-tetrahydro-5H-benzocycloheptene was obtained.
