Reaction Steps

The pyrazole acid, prepared as described in Procedure 8 using 5-amino-4-methyl-1-phenyl-1H-pyrazole-3-carboxylic acid ethyl ester (prepared as described in Procedure 41 using 3-cyano-3-methyl-2-oxopropanoic acid ethyl ester (U.S. Pat. No. 4,652,669)) in place of compound 20 and 2-fluorobenzoyl chloride in place compound 21, was coupled to 2-(3,4,5,6-tetrahydro-2H-[1,4′]bipyridin-4-yl)ethylamine (prepared as described in Procedure 14) using the method of Procedure 10.
