Phosphorus oxychloride (44 μl, 0.47 mmol) was added to a solution of 2-[1-(3-fluorobenzyl)-2-methyl-1H-pyrrolo[2,3-c]pyridin-7-yl]-1,2,3,4-tetrahydroisoquinoline hydrochloride (115 mg, 0.31 mmol) prepared in Example 613 in N,N-dimethylformamide (2 ml). The reaction mixture was stirred overnight at 100° C. under heating. The reaction mixture was cooled to room temperature, added to ice water, basified with a sodium bicarbonate solution, and then extracted with ethyl acetate. The organic layer was dried on anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography (ethyl acetate/n-hexane=1/1, v/v). The resulting product was dissolved in ethyl acetate, saturated with hydrochloric acid gas, and then filtered to give 28 mg of the titled compound as a white solid.
