In a microwave reaction vessel 4-chloro-3-nitro-2-pyridinamine (125 mg) and (3R,4R)-1-benzyl-N,4-dimethyl-3-piperidinamine (314 mg) were suspended in 2-propanol (6.25 mL). To the mixture was added N,N-diisopropylethylamine (0.63 mL). The vessel was sealed and reacted in the microwave reactor at 135° C. for 2 hours. The reaction mixture was concentrated under reduced pressure. The residue was purified by column chromatography on silica gel with chloroform and methanol (100:0 to 90:10) to give N4-[(3R,4R)-1-benzyl-4-methyl-3-piperidinyl]-N4-methyl-3-nitro-2,4-pyridinediamine (230 mg) as a yellow amorphous.
