Reaktionsschritte

To a 25 ml volume three-necked flask with Dean-Stark, 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methylhydrazine ((12-2)-(11)-39) (500 mg), toluene (1.75 ml), and 1-(4-methylphenylsulfonyl)-2-propanone (7-2-4) (470 mg) were added. Water was removed by azeotropic distillation at 45-50° C. under 100 mmHg for 1.5 hours. To the mixture, toluene (1.75 ml) was added, and water was removed by azeotropic distillation at 60° C. under 120 mmHg for 6 hours. The reaction mixture was concentrated under reduced pressure to give 1.109 g of 1-[2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl]-1-methyl-2-[1-(4-methylphenylsulfonyl)-2-propylidene]hydrazine ((4-36)-(1)-39).
