Participants

Reaction Steps

A mixture of 20 mg trifluoromethanesulfonic acid 3-amino-2-carbamoyl-thieno[2,3-b]pyridin-4-yl ester and 50 microl of N-benzylpiperazine in 1 mL of dry dioxane was purged with N2 and capped and left at room temperature overnight. The reaction was diluted with EtOAc, washed four times with water, dried and concentrated to dryness in vacuo. The product was purified on a 2 mm silica gel prep plate, developing and eluting the band with MeOH—CH2Cl2 mixtures and then concentrating to dryness. The product was re-dissolved in 5-10% MeOH—CH2Cl2, filtered to remove silica gel, concentrated, and dried in vacuo at 60° C. overnight to provide 7.9 mg of the title compound as a beige solid.
