Application

Isoxazole-5-carbonyl chloride can undergo reaction with 1-benzhydrylpiperazine to give the corresponding 1-benzhydrylpiperazine derivative, which may be used in the treatment of cancer. It can also be used in the synthesis of N-Isoxazole-5-carbonyl-1,3-diphenyl-5-amino-1H-pyrazole, which can act like potent agent in the treatment of neurological and psychiatric illness.
