, (2020/07/08)
The invention provides a synthesis method of (3-cyclopropylpyridin-2-yl) methylamine hydrochloride, and belongs to the technical field of synthesis of organic chemical intermediates. The preparation method comprises the following steps: reacting 3-bromo-2-cyanopyridine with cyclopropylboronic acid, a phosphine ligand, an alkali and a catalyst under the protection of nitrogen, then reacting with hydrogen under the action of the catalyst, reacting with di-tert-butyl dicarbonate and alkali, and finally reacting with an organic solvent solution of hydrogen chloride to obtain a target product (3-cyclopropylpyridin-2-yl) methylamine hydrochloride. The 3-bromo-2-cyanopyridine is prepared by taking 3-bromopyridine as a raw material and carrying out nitrogen oxidation and cyanation. The method is reasonable in process design, simple in experimental operation and easy to control.
