Base catalyzed condensation of 1 with 2 gave compounds 3, 3-[1-phenyl-3-(2-pyridy/]-1tf-pyrazol-4-yl]-H2-hydroxyphenyl) prop-2-en-1-ones. Compounds 3 on treatment with DMSO/CuCI2 gave 2-[1-phenyl-3-(2- pyridyl)-1H-pyrazol-4-yl)-3-chloro-4W-chroman-4-ones 4. Compounds 3 on oxidative cyclization with DMSO/l2 gave 2-[1-phenyl-3-(2-pyridyl)-1H-pyrazol- 4-yl]-4W-chroman-4-ones 5. Compounds 3 when heated with hydrazine in dioxan gave 5-(1-phenyl-3-(2-pyridyl)-1H-pyrazol-4-yl)-3-(2-hydroxyphenyl)-4,5-dihydro- pyrazolines 6. The compounds 3,4,5 and 6 were characterized by IR, H NMR and mass spectroscopy. These newly synthesized compounds were tested for their antimicrobial activities. Source
