PROCEDURE

实验过程

In 500 mL of ethanol, 3.20 g (5.67 mmol) of the 2-[6-[3-[4-(diphenylmethoxy)piperidino]propylamino]imidazo[1,2-b]pyridazin-2-yl]-2-methylpropionic acid dihydrate obtained in Example 135A was dissolved under heating, followed by concentrating at atomospheric pressure until the total volume became 250 mL. After standing at room temperature, the crystals formed were collected by filtration, washed with ethanol and dried to yield 2.67 g of the title compound.
