実験手順

To a mixed solution of 1-(1-(diphenylmethyl)azetidin-3-yl)-4-methylpiperazine (1.21 g, 3.75 mmol) described in Production Example 3-1 and methanol (20 mL) was added palladium hydroxide-carbon (500 mg) 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 4 hours and 45 minutes. The reaction mixture was purged with a nitrogen atmosphere, and then filtrated using Celite. A filtrate was concentrated under a reduced pressure to give the title compound in the form of a mixture (1.00 g) with benzylbenzene. The product was used in the subsequent reaction without further purification.
