Some tips on 2338-75-2

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 2338-75-2, name is 4-(Trifluoromethyl)phenylacetonitrile, A new synthetic method of this compound is introduced below., Quality Control of 4-(Trifluoromethyl)phenylacetonitrile

Step 1: Preparation of Intermediate 2-(4-Trifluoromethyl-phenyl)-ethylamine (I-16a) (4-Trifluoromethyl-phenyl)-acetonitrile (2 g, 10.81 mmol) in methanolic ammonia (50 mL) was added to Raney nickel (400 mg) in methanol taken in a parr hydrogenator. The flask was stirred at 50 PSI overnight. The reaction was monitored by TLC (10% methanol in CHCl3). The reaction mixture was filtered through celite bed and the filtrate was dried under reduced pressure to afford 2 g of the product (97.89% yield). LCMS purity: 98.73%, m/z=190.0 (M+1)

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
