合成路线1
该中间体在本合成路线中的序号:(V)Acylation of methyl pipecolinate (I) with methyl oxalyl chloride (II) provides oxamate (III). Subsequent addition of 1,1-dimethylpropylmagnesium chloride (IV) to oxamate (III) gives rise to keto amide (V). The methyl ester group of (V) is then hydrolyzed by means of LiOH, yielding the intermediate carboxylic acid (VI)
