Procedure
To a mixed solution of 1-(1-(diphenylmethyl)azetidin-3-yl)-4-ethylpiperazine (12.7 g, 37.9 mmol) described in Production Example 1-3-1 and methanol (50 mL) was added palladium hydroxide-carbon (5.00 g) at room temperature. The resultant mixture was stirred under a hydrogen atmosphere at room temperature and at 0.35 MPa to 0.40 MPa for 10 hours. The reaction mixture was purged with a nitrogen atmosphere and was then filtrated using Celite. A filtrate was concentrated under a reduced pressure to give the title compound in the form of a mixture (12.4 g) with benzylbenzene. The product was used in the subsequent reaction without further purification.
