Analyzing the synthesis route of 846021-26-9

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. 846021-26-9, 2-Amino-6-methylnicotinic acid, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 846021-26-9 ,Some common heterocyclic compound, 846021-26-9, molecular formula is C7H8N2O2, 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.

A mixture of 2-Amino-6-methyl-1licotinic acid (1.44 g, 9.46 mmol) and formamide (8.0 g, 178 mmol) was stirred at 170C for 2 hours. After cooling, the mixture was quenched with water (4 mL). The precipitate was filtered, washed with water and dried to afford 7-Methyl-pyrido [2,3-d] pyrimidin-4-ol (0.79g, 51%). 1H NMR (CDC13, 400 MHz) 8 8.49 (d, J=8.4Hz, 1H), 8.22 (s, 1H), 7.35 (d, J=8. 0Hz, 1H), 2.75 (s, 3H). MS (APCI+) [M+H] +162.

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. 846021-26-9, 2-Amino-6-methylnicotinic acid, other downstream synthetic routes, hurry up and to see.
