Procedure

A solution of sodium methoxide (0.9 g) in ethanol (5 cm3) was added dropwise to a stirred suspension of guanidine hydrochloride (1.58 g) and ethyl (RS)-4-dimethylamino-3-formyl-2-(1-methylethyl)-3-butenoate in ethanol (10 cm3). The reaction mixture was heated at the reflux temperature for 2 hours, then stood at the ambient temperature for 70 hours. The solvent was evaporated under reduced pressure and water added to the residue.
