New downstream synthetic route of 933-80-2

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,933-80-2, its application will become more common.

Electric Literature of 933-80-2 ,Some common heterocyclic compound, 933-80-2, molecular formula is C5H7ClN4, 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.

Step 2: A solution of 6-chloro-2-methylpyrimidine-4,5-diamine (474 mg, 3.0 mmol ) in trimethoxymethane (15 mL) was heated to reflux overnight. The reaction mixture was concentrated and water was added, extracted with EtOAc. The organic layer was separated and washed with water and brine, dried over a2S04 and concentrated. Purification by a flash column chromatography (0-30% EtOAc in petroleum ether) gave 6-chloro-2-methyl-9H- purine (250 mg, 50% yield). LC-MS: m/z 169 (M+H)+.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,933-80-2, its application will become more common.

A mixture of 6- chloro-4,5-diamino-2-methylpyrimidine (317 mg, 2.0 mmol) and l,4-dioxane-2,3-diol (240 mg, 2.0 mmol) in EtOH (15 mL) was stirred at 25 0C for 1 h. TLC analysis (1 :1hexane/EtOAc on SiO2) indicated complete consumption of starting material. l-(4- Methoxyphenyl)-ethylamine (332 mg, 2.2 mmol) and triethylamine (Et3N; 0.3 mL, 2.2 mmol) were added, and the reaction was stirred overnight. The majority of solvent was removed in vacuo and the residue was partitioned between EtOAc and H2O. The organic layer was concentrated in vacuo to leave a brown residue that was purified by column chromatography over SiO2, eluting with 2:1 EtOAc/hexane, then 100% EtOAc to afford [l-(4- methoxyphenyl)ethyl]-2-methylpteridin-4-yl-amine (126 mg) as a brown oil.
