(E)-3-(二甲氨基)-1-(呋喃-2-基)-2-甲基丙-2-烯-1-one

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Two and 73 hundredths grams of [3-(1H-imidazol-1-yl)phenyl]guanidine, dihydrochloride (2) from Example 1, 1.6 grams of 3-dimethylamino-1-(2-furyl)-2-methyl-2-propen-1-one, 25 ml of n-propanol and 2 equivalents (2 ml) of 10N NaOH at pH=11 is refluxed for twenty-four (24) hours. The products are isolated by quenching the reaction mixture including any precipitated solids into water followed by filtration. These filtered solids are re-suspended in water to remove inorganic salts, filtered and air dried to give 1.35 g (44.5% yield) of the desired product, mp 175°-178° C. The products are isolated by quenching the reaction mixture followed by filtration to remove inorganic salts filtered air dried
