Procedure

3.1 g (13 mmol) of 6-ethoxycarbonyl-7-hydroxy-thieno[3,2-b]pyridin-5(4H)-one and 1.3 g (1.2 eq.) of 1,1-dimethylpropargylamine in 80 ml of EtOH were stirred for 8 hours at 150° C. in an autoclave. The solvent was removed under reduced pressure and the solid residue was stirred with diethyl ether. The solid was filtered off and purified chromatographically (silica gel, methylene chloride/methanol=8/1).

Workup

  1. customThe solvent was removed under reduced pressure
  2. filtrationThe solid was filtered off
  3. custompurified chromatographically (silica gel, methylene chloride/methanol=8/1)
