A new synthetic route of 3438-61-7

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. 3438-61-7, 5-Amino-4-methylpyrimidine, other downstream synthetic routes, hurry up and to see.

Related Products of 3438-61-7 ,Some common heterocyclic compound, 3438-61-7, molecular formula is C5H7N3, 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.

4-methylpyrimidin-5-amine (1.09 g, 10 mmol) was dissolved in dry THF (150 mL) under nitrogen. The solution was cooled to -78C and a solution of n-BuLi was added dropwise. The solution was kept at the same temperature for 30min and then warm to r.t., stirred for 2h. Then cooled to -78C, ethyl benzoate (1.5 g, 10 mmol) in THF (30 mL) was added, and the resulting mixture was stirred at -78C for 30min, and was warmed to r.t. for lh. The reaction mixture was quenched with drop some water, and neutralized with NaHC03. EtOAc and water were added, portioned. The organic layer was concentrated and purified by by flush column chromatography on silica gel (eluting with petroleum ether/ethyl acetate =100/1-0/1), to give the title product 6-phenyl-5H-pyrrolo[3,2-d]pyrimidine (0.8 g, 41%). MS (ESI) m/z :196.1 [M+1]+.
