Synthetic Route of 115652-52-3, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 115652-52-3 as follows.
8.3 [1-(2-chloro-6,7-dihydrothieno[3,2-d]pyrimidin-4-ylamino)-cyclopropyl]-methanol (III-4) 1.4 g (II) are placed in 10 ml dioxane, first 3.6 ml diisopropylethylamine, then 1 g of 1-aminocyclopropanmethanol (see 8.2) are added. The reaction mixture is heated to 160 C. until there is no further reaction and after cooling evaporated down. The residue is treated with cyclohexane/ethyl acetate (8:2) in the ultrasound bath and the solid is suction filtered and dried. 1.24 g (III-4) are obtained as a solid. Analytical HPLC-MS (method A): RT=1.01 min.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,115652-52-3, its application will become more common.
