Uses
Diflufenzopyr (SAN 835H) is an auxin transport inhibitor. Diflufenzopyr can enhance the activity of auxin herbicides, such as quinclorac (HY-B0871) and picloram (HY-B2034), and of the synthetic auxin, 1-naphthaleneacetic acid (HY-18570)[1][2].
Synthesis
Diflufenzopyr was prepared as follows: 5 ml of methanol solution containing 4-phenylaminourea (0.37 g, 2.4 mmol) was added to an aqueous solution of 2-acetylnicotinic acid (0.40 g, 2.4 mmol) in 7 ml of methanol, the mixture was stirred at room temperature overnight, thereafter the solid precipitate was collected by filtration, washed with ethanol, and dried to afford 4-phenylsemicarbazone 2-acetylnicotinic acid with a melting point of 174 (decomposition).
