Reaction Steps

10.5 g. (0.05 mole) of ethyl γ-bromo-α-methylbutyrate is combined with 17.0 g. (0.20 mole) of piperidine and 100 ml. of benzene, stirred for 16 hours at room temperature and heated at 60° C. for 4 hours. The reaction mixture is cooled and the colorless solid which appeared is removed by filtration. The mother liquor is concentrated to give ethyl α-methyl-γ-piperidinobutyrate as a mobile yellow liquid which distills (b.p. 78° at 0.25 mm.) as 6.7 g. (63%) of colorless liquid.
