실험 절차

To a solution of 4-dimethylaminomethylene-2,2,5,5-tetramethyl-dihydro-furan-3-one (1.97 g, 10.0 mmol, 1.0 equiv) and guanidine acetate (1.19 g, 10.0 mmol, 1.0 equiv) in ethanol (40 mL) was added sodium methylate (0.54 g, 10.0 mmol, 1.0 equiv) and the reaction mixture heated to 100° C. for 3 h. The solvent was removed under reduced pressure and the reaction product purified by crystallization from a mixture of hot heptane/ethyl acetate to yield 1.3 g (67% yield) of the title compound. MS (EI): 193 [M]+.
