Versuchsvorschrift

Step A—A solution of 4-methyl-N-phenyl-3-oxopentanamide, 12, (5 mmol), 4-benzyloxybenzaldehyde (5 mmol) and pyridine (1 mL) in xylene (100 mL) is heated at reflux, with azeotropic removal of water. The progress of the reaction is monitored by tlc. When the reaction is complete, the solvent is removed under reduced pressure, and the residue is chromatographed to afford 2-(4-benzyloxyphenylmethylene)-4-methyl-3-oxopentanamide, 13, (R=4-benzyloxy).
