Adding a certain compound to certain chemical reactions, such as: 5335-05-7, name is Chloromethyl benzoate, belongs to esters-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 5335-05-7, Safety of Chloromethyl benzoate
To a stirred mixture of with NaH (60%, 50 mg, 1.3 mmole) in anhydrous DMF (6 mL) at room temperature under nitrogen was added 2-(6-(4-(2-(tert-butyl-dimethylsilyloxy)ethyl)piperazin-1-yl)-2-methylpyrimidin-4-ylamino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide, 10 (0.20 g, 0.34 mmole). The resultant mixture was stirred at room temperature for 8 min., then treated with chloromethyl benzoate (0.2 g, 1.2 mmole), the reaction mixture was stirred at room temperature overnight. The reaction mixture was added with aqueous NH4Cl solution and extracted with EtOAc (3×45 mL). The EtOAc solution was washed with 10% LiCl solution and concentrated to an oily residue. The residue was purified by prep. HPLC to give a white solid as impure product and used directly in next step. MS (ESI, M+H+) 736, 738.
