Procedure

Potassium tert-butoxide (15 mg, 0.12 mmol) was added to a solution of 2-[2,3-dimethyl-5-(4-methylpiperazin-1-ylmethyl)-1H-pyrrolo[2,3-c]pyridin-7-yl]-1,2,3,4-tetrahydroisoquinoline (30 mg, 0.074 mmol) prepared in Step 1 of Example 874 and 18-crown-6 (3.1 mg, 0.012 mmol) in anhydrous tetrahydrofuran (2 ml). The reaction mixture was stirred for 1 hour at room temperature and then 3-chlorobenzyl chloride (15.2 μl, 0.12 mmol) was added thereto. The reaction mixture was stirred overnight at room temperature and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/n-hexane=1/5, v/v). The resulting product was dissolved in ethyl acetate, saturated with hydrochloric acid gas, and then filtered to give 21.0 mg of the titled compound as a white solid.
