Triethylamine → HCID 21887383, compound

Participants

Reaction Steps

Methanesulfonyl chloride (0.108 ml) was added to a solution of 1-(3-amino-4-methoxyphenyl)-3-{1-[2-(2-ethoxyphenoxy)ethyl]-4-piperidinyl}-1-propanone dihydrochloride (300 mg) obtained in Example 327 and triethylamine (0.195 ml) in tetrahydrofuran (10 ml) at room temperature, the mixture was stirred for 12 hours, and the reaction mixture was concentrated under reduced pressure. Water (30 ml) and ethyl acetate (40 ml) were added to the residue, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The resulting residue was purified by silica gel chromatography (eluting solvent; ethyl acetate-methanol (9:1)) to give a free base compound of the title compound as a colorless oil (291 mg). The free base compound (290 mg) was treated with a hydrogen chloride-ethanol solution to give the title compound (277 mg) as colorless amorphous powders.
