Application of 72788-94-4, The chemical industry reduces the impact on the environment during synthesis 72788-94-4, name is 2-Chloro-5-(hydroxymethyl)pyrazine, I believe this compound will play a more active role in future production and life.
To a solution of Intermediate 112A (2.00 g, 13.84 mmol) in CHCl3 (20 mL) was added active manganese dioxide (4.81 g, 55.3 mmol) and the resulting suspension was refluxed for 2 h. The reaction mixture was cooled to ambient temperature, filtered through Celite and washed with CHCl3 (200 mL). The combined filtrates were washed with brine (200 mL), dried over anhydrous sodium sulfate and evaporated under reduced pressure. The residue was purified by silica gel column chromatography (Redisep-24 g, 20-30 % EtOAc/ n-hexane) to obtain Intermediate 112B (1.00 g, 50.70%) as a white solid.1H NMR (400 MHz, DMSO-d6) delta ppm 8.98 (d, J = 1.51 Hz, 1 H), 9.04 (d, J = 1.51 Hz, 1 H), 10.07 (s, 1 H). LCMS: The compound did not ionize well.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Chloro-5-(hydroxymethyl)pyrazine, other downstream synthetic routes, hurry up and to see.
