Hydrochloric Acid → HCID 17749871, compound

Participants

Reaction Steps

3.71 g of N-methyl-N-(3-pyridylmethyl)trifluoroacetic acid amide was dissolved in a mixture of 20 ml methanol and 20 ml water, and then stirred with 1.36 g of sodium hydroxide at room temperature for 6 hours. The reaction mixture was made acidic (pH 2) with concentrated hydrochloric acid on ice, and the resulting acidic solution was concentrated under reduced pressure to give a residue. After addition of ethanol, the residue was filtered to remove the precipitated inorganic salts. The filtrate was concentrated under reduced pressure, dried and then recrystallized from methanol/ethanol to give 3-(methylaminomethyl)pyridine dihydrochloride (3.16 g, 95%).
