4570-41-6, Benzo[d]oxazol-2-amine is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,4570-41-6
Step 2:To a solution of 2,3-bis-(4-fluoro-phenyl)-propionic acid (411 mg, 1.57 mmol) and 2-aminobenzoxazole (221 mg, 1.65 mmol) in CH2Cl2 (75 mL) was added DMAP (61 mg, 0.5 mmol) and EDC.HCl (380 mg, 2 mmol).The reaction mixture was stirred at room temperature 7 days, poured onto 0.1percent aqueous HCl and extracted 3 times with CH2Cl2.The combined organic extract was dried over Na2SO4 and concentrated in vacuo.Purification by chromatography (silica, 10-15percent ethyl acetate/hexanes stepwise gradient) followed by trituration with 5percent CH2Cl2 in ether afforded N-benzooxazol-2-yl-2,3-bis-(4-fluoro-phenyl)-propionamide (289 mg, 49percent): LC/MS-ESI observed [M+H]+ 379.
The synthetic route of 4570-41-6 has been constantly updated, and we look forward to future research findings.
