Procedure

To the resulting 1-(4-ethylpiperazin-1-yl)-3-{4-[2-trityloxy-1-(S)-methylethoxy]phenyl}isoquinoline (1.21 g) were added benzene (10 ml), methanol (50 ml) and 2N hydrochloric acid (10 ml) and dissolved, and the resulting mixture was stirred at room temperature for 45 min. The solvent was evaporated, and the resulting residue was adjusted to pH 10 by a 8N aqueous solution of sodium hydroxide, which was then extracted with ethyl acetate. The extract was washed with brine and dried over magnesium sulfate. The solvent was evaporated, to give 0.36 g of the free compound of the title compound as a colorless amorphous.
