851768-35-9, 5-Amino-3-methylbenzo[d]isoxazole is a Benzisoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Synthesis of 3-chloro-2-methyl-N-(3-methyl-benzo[d]isoxazol-5-yl)- benzenesulfonamide, STX 874 (KRB01027):; To a solution of 3-chloro-2-methylbenzenesulphonyl chloride (128 mg, 0.567 mmol) in dichloromethane (3 mL) was added pyridine (110 muL, 1.35 mmol) and the mixture was stirred under N2 for 5 min, after which time 5-amino-3-methyl-1, 2-benzisoxazole [26] (80 mg, 0.54 mmol) was added. The resulting mixture was stirred for 4 h at room temperature, then saturated NaHCO3 solution (8 mL) was added and the mixture was extracted into ethyl acetate (15 mL). The organic phase was washed with brine, dried (Na2SO4), filtered and evaporated to give a residue that was purified using flash chromatography to afford a white solid (88 mg, 48%), single spot at Rf 0.58 (1: 1 hexane: ethyl acetate). mp 162.8-163. 2C, HPLC purity 99+% (tR 2.26 min in 10% water- acetonitrile).’H NMR (CDC13) : 6 7.80 (1H, dd, J=7.9, 1.3 Hz), 7.55 (1H, dd, J=8. 1, 1.1 Hz), 7.38 (2H, m), 7.17 (1 H, t, J=8.1 Hz), 7.10 (1H, dd, J=8.8, 2.2 Hz), 6.72 (1H, s, N-lez 2.72 (3H, s), 2.50 (3H, s). LCMS: 320.00 (M-CH3). FAB-MS (MH+, C15H13ClN2O3S) : calcd 337.0413, found 337.0422.
As the paragraph descriping shows that 851768-35-9 is playing an increasingly important role.
