Adding a certain compound to certain chemical reactions, such as: 53518-15-3, name is 7-Amino-4-(trifluoromethyl)-2H-chromen-2-one, 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 53518-15-3, SDS of cas: 53518-15-3
A vial was charged with S6 (20 mg, 0.027 mmol), 7-amino-4-(trifluoromethyl)coumarin (19 mg, 0.08 1 mmol, 3 eq.), HATU (31 mg, 0.081 mmol, 3 eq.), Et3N (76 1iL, 0.543 mmol, 20 eq.) and DIvIF (500 jiL). Contents were stirred at room temperature and ambient atmosphere for 24 h, after which the solvent was concentrated to dryness, and the crude product was purified via reverse phase HPLC (10-95% MeCN/H20, linear gradient, with constant 0.1% v/v TFA additive; 23 mm run, 42 mL/min flow, detection at 550 nm) to afford S7 (8 mg, 31%). LRMS (ESI) calcd for C46H40F3N30I2S2 [Mj 948.0, found 948.1
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 7-Amino-4-(trifluoromethyl)-2H-chromen-2-one, other downstream synthetic routes, hurry up and to see.
