Methanesulfonic Acid → HCID 86595576, compound

Participants

Reaction Steps

To a solution of (−)-8-[4-(2-butoxyethoxy)phenyl]-1-propyl-N-[4-[[(1-propyl-1H-imidazol-5-yl]methyl]sulfinyl]phenyl]-1,2,3,4-tetrahydro-1-benzoazocine-5-carboxamide (201.5 mg) in ethyl acetate (4 ml) was added methanesulfonic acid (28.9 mg) at room temperature, and the mixture was stirred at room temperature overnight. The resultant was concentrated under reduced pressure, and the precipitated crystals were collected by filtration. The crystals were washed with ethyl acetate to give (S)-(−)-8-[4-(2-propoxyethoxy)phenyl]-1-propyl-N-[4-[[(1-propyl-1H-imidazol-5-yl]methyl]sulfinyl]phenyl]-1,2,3,4-tetrahydro-1-benzoazocine-5-carboxamide/methanesulfonate (118.6 mg) (Compound 45) as yellow crystals.
