---|---|---|
31% | With hydrogenchloride; tin(II) chloride hydrate; acetic acid In water at 100℃; for 1 h; | Step 33.3: 3-methylbenzo[d]isoxazol-5-amine To a stirred solution of 3-methyl-5-nitrobenzo[d]isoxazole (Step 33.2) (1.8 g, 10.10 mmol) in AcOH (40 mL) was added a solution of tin(II) chloride dihydrate (6.84 g, 30.3 mmol) in HCl (15 mL, 494 mmol). The reaction mixture was stirred for 1 hr at 100° C., quenched with a saturated aq. NaHCO3 solution, diluted with water, and extracted with CH2Cl2. The combined organic layers were washed once with a saturated aq. NH4Cl solution, dried over Na2SO4 and evaporated. The crude material was purified by silica gel column chromatography (hexane/EtOAc 20-50) to afford the title product (458 mg, 3.09 mmol, 31percent yield) as a pink solid. tR: 0.50 min (LC-MS 2); ESI-MS: 149 [M+H]+ (LC-MS 2); Rf=0.45 (hexane/EtOAc 1:1). |
