実験手順
Then, 8.16 g of the 1-benzoyl-4-hydroxypiperidine and 3.53 g of diketene were reacted similarly as in Reference Example 1, and the reaction mixture was concentrated to obtain 12.0 g of almost pure oily acetoacetic acid-N-benzoyl-4-piperidinyl ester on thin layer chromatography. This was used directly in the reaction of Example 3.
