1990-90-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 1990-90-5, name is 3-Methylpyridin-4-amine, molecular formula is C6H8N2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a solution of intermediate 23d (100 mg) in CH2Cl2 (7 mL) were at 0 C. consecutively added N,N-diisopropyl ethylamine (140 muL), 3-methylpyridin-4-amine (40 mg) and bromotripyrrolidino phosphonium hexafluorophosphate (230 mg) and the resulting mixture was stirred at ambient temperature for 2 h. The volatiles were removed under reduced pressure and the residue was purified by column chromatography (Interchim cartridge 15SiHP/25 g, Cy/EtOAc) to yield the desired compound (84% yield). [0490] LC-MS (Method 2): m/z [M+H]+=341.1 (MW calc.=340.81); Rt=0.57 min.
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. 1990-90-5, 3-Methylpyridin-4-amine, other downstream synthetic routes, hurry up and to see.
