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. SDS of cas: 16034-46-1
To a solution of 1 -methyl- lH-pyrazole-5-carboxylic acid (2 g, 15.86 mmol) in tetrahydrofuran (50 mL) was added L1AIH4 (720 mg, 18.97 mmol) in portions at 0 C under an inert atmosphere of nitrogen. The reaction was stirred for 2 hours at room temperature then quenched by the addition of water (2 mL). The mixture was dried over by anhydrous sodium sulfate and the solids were filtered out. The filtrates were concentrated under reduced pressure to afford (1 -methyl- lH-pyrazol- 5-yl)methanol as colorless oil (1.2 g, 67 ). (ES, m/z) [M+H]+ 113.0 *H NMR (300 MHz, CDC13) delta 7.36 (d, 7 = 1.8 Hz, 1H), 6.18 (d, 7 = 1.8 Hz, 1H), 4.66 (s, 2H), 3.88 (s, 3H)
The synthetic route of 16034-46-1 has been constantly updated, and we look forward to future research findings.
