| titleOfInvention | Method for producing 1-methylpyrrolidin-3-ol |
| abstract | The invention relates to a method of producing compound (I) n n n n n n n n n n by (A) reacting compound (II) n n n n n n n n n n formaldehyde and hydrogen in the presence of a metal catalyst, in a solvent, wherein the amount of the formaldehyde to be used is exceeding 1 mol and not exceeding 5 mol per 1 mol of compound (II), to obtain a mixture containing the formaldehyde and compound (I), and (B) mixing the obtained mixture containing the formaldehyde and compound (I) with hydrogen and a secondary amine selected from the group consisting of diethylamine, dipropylamine, diisopropylamine, butylethylamine, pyrrolidine, piperidine and morpholine, in the presence of a metal catalyst, in a solvent, and then removing the metal catalyst, followed by obtaining the compound (I) by distillation. |
