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. 34253-03-7, name is Methyl pyrimidine-2-carboxylate, the common compound, a new synthetic route is introduced below. Product Details of 34253-03-7
Step B: Preparation of pyrimidin-2-ylmethanol: NaBH4 (0.22 g, 5.79 mmol) was added in one portion to a solution of methylpyrimidine-2-carboxlate (0.80, 5.79 mmol) in EtOH (30 mL). The reaction mixture was left at room temperature overnight before carefully quenching with water (5.0 mL) and concentrating to dryness. The residue was taken up in MeOH and filtered. The filtrate was concentrated and was purified by flash column chromatography, eluting with CH2Cl2/MeOH (100:1) to give 0.18 g (28%) of the desired product as a yellow oil. Step B: Pyrimidin-2-ylmethanol: A solution of methyl pyrimidine-2-carboxylate (659 mg, 4.77 mmol, 1.00 equiv) in 25 mL EtOH was cooled to 0 C. in an ice bath, and sodium borohydride (181 mg, 4.77 mmol, 1.00 equiv) was added. The reaction mixture was warmed to ambient temperature, and stirred 2 hours, and then 5 ml water was added. The reaction was concentrated under reduced pressure, and the residue was purified using silica gel chromatography to give the desired product as a white solid (154 mg, 30%).
The synthetic route of 34253-03-7 has been constantly updated, and we look forward to future research findings.
