- Patent Document 3 Japanese Patent No. 2965675
- Patent Document 1 and Patent Document 2 it is disclosed in Examples that the compound of the formula (IV) is converted to the compound of the formula (I) by catalytic hydrogenation using 10% noradium carbon as a catalyst. Due to insufficient reaction selectivity, the reaction products are purified by column chromatography. It was necessary to make.
- Patent Document 3 the objective is to produce an optically active compound of formula (I) by asymmetric hydrogenation.
- a homogeneous catalyst is used, at least a separation operation is required to remove the catalyst. This is disadvantageous in terms of time and cost as an industrial manufacturing method. Therefore, there has been a demand for a process for producing a compound of formula (I) or a salt thereof that is easy to operate and suitable for industrial production.
- the present inventors have found a simpler method for producing a highly pure compound of formula (I) or a hydrochloride thereof.
- reaction point (a) There is a reaction point (a), but there is a reaction point (d). If only the reaction point (a) is selectively hydrogenated, the desired compound of formula (I) is obtained. When the compound of formula (ii) is subjected to catalytic hydrogenation using a commonly used catalyst, hydrogenolysis proceeds at the same time, particularly in (b).
- the present inventors have suppressed side reactions such as the hydrogenolysis reaction by using a palladium-alumina catalyst and selecting reaction conditions, so that the compound of the formula (I) or its hydrochloride is highly purified. And found that it can be obtained in high yield. As a result, a production method of the compound of formula (I) or its hydrochloride suitable for industrial production with higher purity was completed.

- the solvate means a solvent in which the solvent used for crystallization is incorporated in the crystal lattice at a certain ratio when the compound of the formula ( ⁇ ) is produced. Products, ethanol hydrates, toluene solvates, etc., and can be used as they are as long as they do not inhibit the catalytic hydrogenation reaction. Similarly, the solvent used for crystallization of the compound of formula ( ⁇ ) or filtration As long as the solvent used for washing at this time does not inhibit the catalytic hydrogenation reaction, it can be used in the reaction as it is without performing a drying operation.
- the noradium-alumina catalyst is not particularly limited, and examples thereof include alumina powder holding 1 to 10% by weight of palladium. 570-2), 5% by weight palladium alumina (20, 571-0) and 10% by weight palladium alumina (44, 008-6) are commercially available and can be used as they are.
- the amount of the palladium-alumina catalyst used is preferably 1 to 20% by weight of the palladium-alumina catalyst with respect to the compound of formula (IV) as the raw material.
- the reaction solvent used does not inhibit the reaction, and is not particularly limited as long as it is used.

It can be carried out by adding a dissolved solution or by adding hydrochloric acid.
- the solution of the compound of formula (I) is a solution obtained by filtering the catalytic hydrogenation reaction solution to remove the catalyst, or a solution obtained by partially concentrating the solution from which the catalyst has been removed is used.
- a solution obtained by removing the catalyst is concentrated and then used in a solution dissolved in a different solvent, or isolated by crystallization and then dissolved in a solvent.
- the solvent used for the formation of hydrochloride is not particularly limited as long as it does not inhibit hydrochloric acid chlorination or crystallization of hydrochloride, and preferably ethanol, tetrahydrofuran or ethyl acetate is used.
