실험 절차

In a separate reaction container, 7-fluoro-2-methyl-3H-benzimidazol-5-yl amine (100 mg, 0.44 mmol), lithium bis(trimethylsilyl) amide (190 mg, 1.1 mmol), and benzophenone hydrazone (94.3 mg, 0.48 mmol) were dissolved in N-methyl-morpholine (0.5 ml) under a nitrogen atmosphere. Then, the prepared solution containing the catalyst was added thereto. After deaeration, this was heated and stirred at 100° C. under a nitrogen atmosphere for two hours. The reaction mixture was cooled to room temperature, and then an aqueous solution of 6 M hydrochloric acid (0.5 ml) was added thereto. The organic layer was isolated, and concentrated under reduced pressure. Thus, crude N-benzhydrylidene-N′-(7-fluoro-2-methyl-1H-benzimidazol-5-yl)-hydrazine was obtained. The obtained crude product was used in subsequent reactions without being purified.
