Then, (3-methyl- 5,6,7,8-tetrahydro-[l,2,4]triazolo[4,3-a]pyridin-6-yl) methanesulfonate (604 mg, 2.61 mmol, 70% purity) in DMF (4 mL) was added to the solution at 20 C. Then, the mixture was stirred at 80 C for 12 h. The reaction solution was added with NH4Q solution (20 ml,), extracted with DCM:MeOH (20 mL chi 3, ratio=3: l). The organic layers were combined, dried over Na2S04, filtered and concentrated under reduced pressure. The crude product was purified by prep-TLC (DCM:MeOH = 5: 1) to give a mixture of 3-niethy3~6~(3-methyi-4~nitro^ and 3- methyl-6-(5~methyl-4-nitro-pyra^ as a yellow gum.
