A new synthetic route of 639091-75-1

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. 639091-75-1, Methyl 2-(Boc-amino)isonicotinate, other downstream synthetic routes, hurry up and to see.

Electric Literature of 639091-75-1 ,Some common heterocyclic compound, 639091-75-1, molecular formula is C12H16N2O4, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

Compound 2E (2.5 g, 9.91 mmol, 1.00 equiv) and CaC12 (1.65 g) were dissolved in EtOH (30 mL). The solution was cooled to 0C then NaBH4 (1.13 g, 29.87 mmol, 3.01 equiv) was gradually added. The solution was left under agitation overnight atambient temperature then the reaction was halted with the addition of water (50 mL). The mixture was extracted three times with 20 mL of EtOAc. The organic phases were combined, washed twice with 20 mL of NaC1 (sat.) then dried over sodium sulfate, filtered and concentrated under reduced pressure to yield 2.0 g (90 %) of compound 2F in the form of a colourless solid.

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. 639091-75-1, Methyl 2-(Boc-amino)isonicotinate, other downstream synthetic routes, hurry up and to see.
