ABSTRACT OF THE DISCLOSUREThis invention provides a process for preparing2-(3-aryl-5-isoxazol)benzoyl halide having the formulawherein X and Y are independently selected from the groupconsisting of hydrogen, halogen, lower alkyl, lower alkoxy,halo-lower-alkyl, phenoxyphenyl and cyano and wherein X1is a chloro, bromo, fluoro or iodo; which comprises treating3'-(aryl)-spirocisobenzofuran-l(3H)5'(4'H)-isoxazol] 3-onehaving the formulawherein X and Y are as previously defined, with an acidhalide and water. The compounds obtained are effective asplant growth regulants. The process overcomes the need toconvert isoxazolin-5-yl benzoate with N-bromosuccinimide ordichlorodicyanobenzoquinone since isoxazolin-5-yl benzoatesare prepared from vinyl benzoates which are difficult toprepare.
