Reaction Steps

By proceeding in a manner similar to Example 258(a) above but (i) using 3-(5-chloro-6-methyl-1H-benzoimidazol-2-yl)-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine [Example 251(b)] and diethylcarbamyl chloride, and (ii) subjecting the reaction product to flash column chromatography, eluting with ethyl acetate to ethyl acetate/methanol (47:3, v/v) followed by trituration with ethanol, there was prepared 3-(5-chloro-6-methyl-1H-benzoimidazol-2-yl)-1,4,6,7-tetrahydro-pyrazolo[4,3-c]pyridine-5-carboxylic acid diethylamide (35.6 mg) as a pale yellow solid. MS: 387/389 (M+H)+. HPLC (METHOD E1): RT=11.07 minutes.
