실험 절차

The following components were reacted according to General Procedure 1, above: 3-nitro-1,2-phenylenediamine (0.50 g; 3.26 mmoles), 3-fluoro-1,2-phenylenediamine (0.41 g; 3.26 mmoles), diethyl malonimidate dihydrochloride (1.1 eq.; 0.83 g; 3.60 mmoles) and acetic acid (25 mL). The crude mixture of three compounds was then reduced according to General Procedure 2, above. The crude solid product was taken up in 10 mL of dilute HCl, purified by preparative HPLC (25 to 75% acetonitrile (with 0.1% TFA) over 50 minutes) and converted to the HCl salt by three freeze drying cycles with dilute HCl. This procedure gave 0.208 g of pure 2-[(4-fluoro-1H-benzimidazol-2-yl)methyl]-1H-benzimidazol-4-ylamine dihydrochloride in 18% yield. It had MS: m/z=282.2 [M+1] amu and gave one peak on HPLC at both 210 and 280 nm (12.99 minutes using the JWTFACN gradient).
