Reaction Steps
In a procedure analogous to Example 3, reaction of 6-chloro-N-[1-(4-fluorophenyl)ethyl]pyrazin-2-amine (1.80 g, 7.15 mmol) and 5-hydroxymethyl benzimidazole (1.26 g, 8.5 mmol) furnished the two products which were separated by column chromatography using dichloromethane-methanol (98:2-92:8) as eluant. From the less polar fractions was obtained [1-(6-{[1-(4-fluorophenyl)ethyl]amino}pyrazin-2-yl)-1H-benzimidazol-6-yl]methanol as a pale yellow solid (210 mg).
