Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 60144-53-8, name is tert-Butyl (4-fluorophenyl)carbamate, This compound has unique chemical properties. The synthetic route is as follows., Formula: C11H14FNO2

To a solution of 4-fluorophenylcarbamic acid te/t-butyl ester (1.3 g, 6.2 mmol) in anhydrous tetrahydrofuran (15 mL) was added sodium hydride (60% dispersion in mineral oil, 261 mg, 6.8 mmol). After the initial gas evolution had ceased, the reaction was allowed to stir for 15 minutes. Tetra-n-butylammonium iodide (227 mg, 0.6 mmol) was then added followed by addition of the 2-chloro-5-chloromethyl thiazole prepared above. The mixture was heated to reflux for 1 hour. After cooling, the reaction was carefully neutralized with cold saturated sodium bicarbonate (10 mL) and extracted with ethyl acetate (2 x 20 mL). The organic layers were combined, dried over anhydrous sodium sulfate, filtered and the solvent removed under reduced pressure to provide a dark oil. Flash chromatography (silica gel; 5%- 10% ethyl acetate in hexanes) provided 2-chloro-thiazol-5-ylmethyl-4- fluorophenylcarbamic acid te/t-butyl ester (1.5 g, 4.4 mmol) as a yellow oil.

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 60144-53-8.
