実験手順
A mixture from Example 105A (1.56 g, 10.1 mmol), 3-dimethylamino-2-methyl-2-propenal (1.63 g, 14.4 mmol) and acetic acid (25 μL, 0.44 mmol) in ethanol (10 mL) was heated by microwave to 150° C. for 30 minutes. The mixture was cooled to ambient temperature and concentrated. Purification by silica gel chromatography (EtOAc, Rf=0.53) afforded 1.66 g (80%) of the title compound. MS (DCI) m/z 205 (M+H)+.
