Reference of 94220-38-9, Adding some certain compound to certain chemical reactions, such as: 94220-38-9, name is 7-Chloro-5-methyl-1H-pyrazolo[4,3-b]-pyridine,molecular formula is C7H6ClN3, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 94220-38-9.
EXAMPLE 2 5-Methyl-7-piperidino-1H-pyrazolo(4,3-b)pyridine (2) STR15 7-Chloro-5-methyl-1H-pyrazolo(4,3-b)pyridine (1 g) and piperidine (10 ml) were heated under reflux for 24 h. The piperidine was removed in vacuo to yield a pale yellow solid which was washed with water to yield the piperidino-compound (1 g, 78%), Crystallisation from ethanol-water gave pale yellow crystals, m.p. 244. Found: C, 66.5; H, 7.55.; N, 25.7. C12 H16 N4 requires C, 66.6; H, 7.5; N, 25.9%), numax 2660-2200 (broad), 2000-1800 (broad), 1540, 1430, 1355, 1290, 1210, 1020, 980, 810 and 760 cm-1, delta (CF3 COOH) 1.97 (6H, s, –CH2 –), 2.70 (3H, s, 5 –CH3), 4.13 (4H, s, –N–CH2 –), 6.59 (1H, s, 6-H), 8.32 (1H, s, 3-H), total proton count 15.
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. 94220-38-9, 7-Chloro-5-methyl-1H-pyrazolo[4,3-b]-pyridine, other downstream synthetic routes, hurry up and to see.
