Production method

It is obtained by addition reaction of 2-methylpyridine with formaldehyde. Formaldehyde and 2-methylpyridine were added into the reaction pot, and nitrogen was added, stirred and heated to 125℃ with a pressure of about 0.4MPa. After 20h of reaction, vacuum distillation was carried out, and 2-(2-hydroxyethyl) pyridine was obtained by collecting 130-145℃(2.13kPa) fractions.

use

Used in organic synthesis.
