Novel syntheses of the amino-1,2,4-triazine GW356194: identification of a synthesis amenable to scale up
摘要:
New syntheses of the amino-1,2,4-triazine, GW356194 have been developed to improve on existing methodology. The use of different amidrazones in cyclisations with alpha-keto and alpha-amido carbonyl compounds as the key step for the synthesis of the 1,2,4-triazine core was evaluated and the results are presented here.
