Synthetic Route of 918538-05-3, 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. 918538-05-3, name is 2,4-Dichloropyrrolo[2,1-f][1,2,4]triazine belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A mixture of 2,4-dichloropyrrolo[1,2-f][1,2,4]triazine (5.5 g, 29.3 mmol), morpholine (2.8 mL, 32.2 mmol) and K2C03 (8.0 g, 58.6 mmol) in DCM (50 mL) was stirred at room temperature for 3h. The TLC showed the starting material was completely consumed and H20 (50 mL) was added. The mixture was extracted with DCM (50 mL*2).The combined organic layers were washed with brine, dried over Na2SO4 and concentrated in vacuo to obtain 6.5 g of compound 2, yield in 93%. ?H NMR (CDC13, 400MHz): oe 7.58-7.57 (m, 1H), 6.74-6.72 (m, 1H), 6.64-6.62 (m, 1H), 4.05 (t, 4H, J =4.8Hz), 3.84 (t, 4H, J = 5.2Hz). ESI-MS (M+H): 239.
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, 2,4-Dichloropyrrolo[2,1-f][1,2,4]triazine, other downstream synthetic routes, hurry up and to see.
