実験手順
1.1 g of 8-amino-7-[2,3-epoxy-1-oxo-3-(3-thienyl)propyl]-2,3-dimethylimidazo[1,2-a]pyridine are dissolved in 20 ml of hexafluoroisopropanol at room temperature, the solvent is stripped off after 19 hours and the residue is purified on silica gel (eluent: methylene chloride/methanol=100/3). 70 mg of the title compound of m.p. 222-25° C. (diethyl ether) are obtained.
後処理
- customthe residue is purified on silica gel (eluent: methylene chloride/methanol=100/3)
