Monomethylamine methanol → (4-aminomethylbenzyl)-(4-dipropylaminobutyl)carbamic Acid t-butyl Ester

Participants

Reaction Steps

The compound (70.0 mg) obtained in Example 76-2 was added with a 40% methylamine/methanol solution (3.0 ml) and the whole was stirred at room temperature for 14 hours. After completion of the reaction, the solvent was distilled off. The resultant was added with a 1 mol/l sodium hydroxide aqueous solution and chloroform to extract the aqueous layer with chloroform. The resultant was dried with anhydrous sodium sulfate and the solvent was distilled off, thereby obtaining the subject compound (65.5 mg) as a colorless viscous liquid.
