Methyl iodide → HCID 10747204, compound

Participants

Reaction Steps

A solution of 2—(4-piperidinophenyl)-N-(4—((N-tetrahydropyran-4-yl-N-methylamino)methyl)phenyl)-6,7-dihydro-5H-benzocycloheptene-8-carboxamide (0.2 g) and methyl iodide (0.025 ml) in dimethylformamide (10 ml) was stirred at room temperature over night. The solvent was evaporated, and the residue was purified with silica gel column (chloroform/methanol) to give crude crystals, which were recrystallized from ethanol-hexane to give dimethyl-(N-(2—(4-piperidinophenyl)-6,7-dihydro-5H-benzocyclo-heptene-8-carbonyl)-4-aminobenzyl)-4-tetrahydropyranyl-ammonium iodide (Compound 225) (0.15 g) as pale brown crystals.
