16034-46-1<\/a>, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 16034-46-1, name is 1-Methyl-1H-pyrazole-5-carboxylic acid belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.<\/p>\n

To a solution of 5-bromoindoline (200 mg, 1.01 mmol, 1 eq) and 2-methylpyrazole-3-carboxylic acid (127.35 mg, 1.01 mmol, 1.0 eq) in EtOAc (10 mL) was added T3P (1.93 g, 3.03 mmol, 1.80 mL, 50%, 3.0 eq) and DIEA (652.54 mg, 5.05 mmol, 879.44 muL, 5.0 eq). The mixture was stirred at 60 C. for 3 h. The reaction mixture was concentrated under reduced pressure to give a residue which was purified on silica gel column chromatography (from PE\/EtOAc=1\/0 to 10\/3, TLC: PE\/EtOAc=3\/1, Rf=0.42) to give the product (5-bromoindolin-1-yl)-(2-methylpyrazol-3-yl)methanone (300 mg, 960.29 mumol, 95.1% yield, 98.0% purity) as a white solid 1H NMR (400 MHz, CDCl3) delta ppm 8.08 (s, 1H), 7.52 (d, J=2.2 Hz, 1H), 7.30-7.37 (m, 2H), 6.53 (d, J=2.0 Hz, 1H), 4.24 (t, J=8.3 Hz, 2H), 4.08 (s, 3H), 3.18 (t, J=8.3 Hz, 2H); ES-LCMS m\/z 306.0, 308.0 [M+H]+.<\/p>\n
