Synthetic Route of 116855-08-4 ,Some common heterocyclic compound, 116855-08-4, molecular formula is C7H5N3O2, 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.
10330] To a mixture of D-4-01-1 (30 mg, 0.18 mmol)DCM (3 mE) was added oxalyl dichloride (2 mE). The reaction mixture was stirred at r.t. for 3 h. The solution was concentrated and the residue was dissolved in DCM (3 mE). TEA (37 mg, 0.37 mmol) and (R)-2-amino-3-(3-chlorophe- nyl)propanoic acid (36 mg, 0.18 mmol) was then added and the solution was stirred at r.t. overnight. The resultant was concentrated to give D-4-01-5-1 (20 mg, 32%), which was used directly for the next step.
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. 116855-08-4, 1H-Pyrazolo[3,4-b]pyridine-3-carboxylic acid, other downstream synthetic routes, hurry up and to see.
