64037-15-6,64037-15-6, 5-Methyl-2-aminobenzoxazol is a benzoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution of succinic anhydride (141.1 g, 1.41 mol) and 70 g (about 0.47 mol) of compound of step 1a (70 g, 0.47 mol) in 2500 ml of anhydrous toluene was refluxed for overnight. After that, HATU (100 g, 0.26 mol) and 4-methylmorpholine (41.36 ml, 0.376 mol) were added and the resulting mixture was refluxed for 2-3 hours. TLC showed that the major spot was product (Rf=0.35, acetone_hexane=1:2). After reaction was completed, the solvent was evaporated and the residue was dissolved in about 2000 ml of CH2Cl2. The solution was washed with aqueous NaHCO3. After pH was adjusted to 7-8 and washed with brine, organic phase was separated and dried over MgSO4. Filtration and removal of solvent gave the title compound (98 g) as fine white needle crystalline
64037-15-6 5-Methyl-2-aminobenzoxazol 46388, abenzoxazole compound, is more and more widely used in various.
