반응 단계
Under the same conditions as in Example 1, 116 g (1.0 mol) of methyl acetoacetate in a mixture of 520 ml of methylene chloride and 30 ml of methyl ethyl ketone were reacted with 77.8 g (1.05 mol) of calcium hydroxide and 148.0 g (1.1 mol) of hexanoyl chloride. The pH in the subsequent reaction with ammonia was adjusted to 9.2. This gave 165 g (GC purity 78.5%) of methyl hexanoylacetate (yield 75.0%).
