Reaction Steps

To a solution of 70%-allylhydrazine (7.73 ml, 75 mmol) and triethylamine (1048 ml, 75 mmol) in chloroform (25 ml) was added ethyl 2-bromo-2-methylpropanoate (9.75 g, 50 mmol) and the mixture was sittred for 1 hr and then refluxed overnight. The reaction mixture was diluted with ethylacetate (150 ml) and washed with water (100 ml) and brine (100 ml). Then the organic layer was dried over magnesium sulfate and filtered. The filtrate was concentrated in vacuo. The crude residue was subjected to silica gel column chromatography (eluent: chloroform:methanol=95:5) to obtain the title compound (5.0 g, 54%).
