実験手順
Example 5 is repeated except that a mixture of 11.8% by weight of n-butyl α-isocyanopropionate and 88.2% by weight of N,N-dibutylaniline is added continuously via the inlet (A). 4-Methyl-5-n-butoxyoxazole is obtained in a yield of 98.7% via the top takeoff B and the amine via the sidestream takeoff D.
