Reaction Steps

To a solution of 6-amino-3-[N-(4-methoxybenzyl)-3-methylindazol-5-yl]-5-(4-Boc-piperazin-1-yl)-[1,2,4]triazine 111 (0.04 g, 0.0755 mmol) in anhydrous THF (2 mL), cooled at −78° C., was added a 1.0 M solution of lithium bis(trimethylsilyl)amide (0.083 mL) and benzyl bromide (0.001 mL dissolved in 0.1 mL THF). The reaction mixture was allowed to warm to room temperature. The reaction mixture was heated at 70° C. for 3 hours. Dichloromethane (50 mL) was added. The organic layer was washed with 1% citric acid, water and brine. The organic layer was dried over sodium sulfate. The organic solvent was evaporated under reduced pressure. The crude product was purified by RP-HPLC to yield the desired 6-benzylamino-3-[N-(4-methoxybenzyl)-3-methylindazol-5-yl]-5-(4-Boc-piperazin-1-yl)-[1,2,4]triazine 114 (0.027 g, 0.0435 mmol).
