PREPARATION OF 3-AMINO-5(T-BUTYL) ISOXAZOLE |
摘要 |
3-Amino-5-(t-butyl)isoxazole, in optimum yield, is prepared in a stepwise manner by reacting a lower alkyl pivalate and acetonitrile in the presence of a base to yield pivalyl acetonitrile, which in turn is allowed to react with hydroxylamine under controlled conditions of pH to yield the desired compound. The compound is a useful intermediate for the preparation of isoxazole derivatives having utility as herbicides. |
