Procedure

Diethylaminosulfur trifluoride (0.27 g) was added to a solution of 1-(4-ethylpiperazin-1-yl)-3-[4-(1-hydroxypropyl)phenyl]isoquinoline (0.53 g) obtained in Example 19 in methylene chloride (30 ml) at −78° C. After stirring the resulting mixture for 1 hr, it was returned to room temperature. An aqueous solution of saturated sodium bicarbonate and ethyl acetate were added to the resulting reaction solution, for partitioning. The resulting organic layer was washed with water and brine, dried and concentrated. The resulting residue was purified by silica gel column chromatography (methylene chloride/methanol system) (0.38 g), and was then converted into a hydrochloride in a conventional manner, to give 0.36 g of the title compound as a yellow powder.
