Reference of 294877-29-5<\/a>, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 294877-29-5 name is 1-(3-Bromophenyl)-3,5-dimethyl-1H-pyrazole, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.<\/p>\n

Synthesis of N-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)benzenamine A-NH-1DM To a Schlenck tube equipped with a magnetic stir bar and a condenser was added 1-(3-bromophenyl)-3,5-dimethyl-1H-pyrazole A-Br-1DM (1507 mg, 6.0 mmol, 1.0 eq), tBuONa (923 mg, 9.6 mmol, 1.6 eq), Pd2(dba)3 (110 mg, 0.12 mmol, 0.02 eq), JohnPhos (72 mg, 0.24 mmol, 0.04 eq), and toluene (24 mL) under nitrogen. The mixture was stirred in an oil bath at a temperature of 85-95 C. for 46 hours then cooled down to ambient temperature. The solvent was removed and the residue was purified through column chromatography on silica gel using hexane\/ethyl acetate (3:1) as eluent to obtain the desired product N-(3-(3,5-dimethyl-1H-pyrazol-1-yl)phenyl)benzenamine A-NH-1DM as a brown liquid 1.48 g in 94% yield. 1H NMR (DMSO-d6, 400 MHz): delta 2.16 (s, 3H), 2.30 (s, 3H), 6.04 (s, 1H), 6.87-6.90 (m, 2H), 7.04 (dd, J=7.6, 2.0 Hz, 1H), 7.11-7.13 (m, 3H), 7.25-7.32 (m, 3H), 8.36 (s, 1H).<\/p>\n
