Reaction Steps

A mixture of 11-9 (220 mg, 0.8619 mmol), 1-4, 2-amino-3-formylpyridine (137 mg, 1.12 mmol) and proline (99 mg, 0.8619 mmol) in absolute ethanol (5 mL) was heated at reflux for 12 h. Following evaporative removal of the solvent, the residue was chromatographed (silica gel, 70:25:5 chloroform/ethyl acetate/MeOH) to give 11-10 as a yellow oil.
