Reaction Conditions

Reaction Steps

1,5-dimethyl-1H-1,2,4-triazol-3-amine (170 mg, 1.517 nmmol) was taken up in 6 ml of anhydrous THF and cooled to 0° C. Sodium tert-butoxide (243 mg, 2.53 mmol) was added and the reaction was stirred at 0° C. for 5 min. Next, a solution of 2,4-bis(methylthio)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Intermediate (300 mg, 1.264 mmol) in 8 ml of THF was added, and the reaction was brought to rt. The reaction was stirred at room temperature for 1 h. The solvent was removed in vacuo and the material was dissolved in EtOAc. The organic layer was washed once with water, and the aqueous layer was re-extracted with EtOAc. The organic layers were combined, washed with brine, dried over Na2SO4, filtered and concentrated to give 4-((1,5-dimethyl-1H-1,2,4-triazol-3-yl)amino)-2-(methylthio)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (157 mg) as a yellow solid. The crude material was taken onto the next step without further purification.
