(4-丙-2-基苯基)甲基肼

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

实验步骤: 32 g of p-isopropylbenzylhydrazine were added, under nitrogen, to a solution of 31.8 g of β-amino-β-ethoxyacrylic acid ethyl ester and 1 g of p-toluenesulphonic acid in 150 ml of ethanol. After stirring for a further two hours, the mixture was left to stand overnight. The compound identified above, which separated out as a precipitate, was filtered off and recrystallised from ethanol. Melting point: 105°, 18.3 g (40%). the mixture was left to stand overnight separated out as a precipitate was filtered off recrystallised from ethanol
