Method: The 4-benzyl-3-methyl-1 - (3-nitrophenyl) - 1H-pyrazol-5-ol derivatives were synthesized through the reduction reaction of 4-benzylidene-3-methyl-1 - (3-nitrophenyl) - 1H-pyrazol-5 (4H) - on with sodium borohydride.
Đối tượng – phương pháp nghiên cứu: Dẫn chất 4 - benzyl-3 - methyl-1 - (3 - nitrophenyl) -1 H-pyrazol -5 - ol được tổng hợp thông qua phản ứng khử hoá 4 - benzyliden-3 - methyl-1 - (3 - nitrophenyl) -1 H-pyrazol -5 (4 H) - on bằng natri borohydrid.
