反応手順

18-Crown-6 (2.5 mg, 0.0097 mmol) and potassium tert-butoxide (33 mg, 0.291 mmol) were added to a solution of 2,3-dimethyl-7-(4-vinylphenyl)-1H-pyrrolo[2,3-c]pyridine (24 mg, 0.097 mmol) prepared in Example 242 in anhydrous tetrahydrofuran (0.5 ml). The reaction mixture was stirred for 30 minutes at room temperature and 3-fluorobenzyl chloride (20 μl, 0.16 mmol) was added thereto. The reaction mixture was stirred overnight and then concentrated under reduced pressure. The resulting residue was purified with silica gel column chromatography. The resulting product was dissolved in ethyl acetate, saturated with hydrochloric acid gas, and then filtered to give 3.8 mg of the titled compound as a white solid.
