Related Products of 1597-32-6, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1597-32-6, name is 2-Amino-6-fluoropyridine, molecular formula is C5H5FN2, molecular weight is 112.11, as common compound, the synthetic route is as follows.
General procedure: To the solution of Acid SM-IX (750 mg, 2.i8 mmol, iOO mol-%) in dry DCM (iO ml) under nitrogen atmosphere was added 3-amino-5- methylisoxazole (427 mg, 4.36 mmol, 200 mol-%) and pyridine (526 p1, 6.53mmol, 300 mol-%). T3P (50 w-% in EtOAc) (2.6 ml, 4.36 mmol, 200 mol-%) was added dropwise and the reaction mixture stirred at rt for four hours. DCM (i 0 ml) and i 0 % NaH 003 (30 ml) were added. The water phase was extracted twice with DCM (2 x iO ml). The organic phases were combined and washed with 0.i N HCI solution (3 x 30 ml), water (3 x 30 ml) and finally withbrine (3 x 30 ml) and dried with sodium sulfate. The crude yield of compound i was 95 % (875 mg).1H NMR (200 MHz, DMSO-d6): 0.97 (5, 3 H), i.24 -2.46 (m, i6 H),2.37 (5, 3H), 2.58 – 3.Oi (m, 2 H), 6.64 (5, i H), 6.88-7.06 (m, i H), 7.07 – 7.25 (m, 2 H), iO.88 (5, i H).
The chemical industry reduces the impact on the environment during synthesis 1597-32-6, I believe this compound will play a more active role in future production and life.
