3-BROMO-5-ISOXAZOLECARBOXALDEHYDE Use and Manufacturing
To a solution of To a chilled (O0C) solution of 3-bromo-isoxazol-5-yl)-methanol (560 mg, 3.15 mmol) in CH2Cl2 (31 niL) was added Dess-Martin periodinane (2.00 g, 4.72 mmol) in 3 portions and the mixture was warmed to room temperature. After 4 hours, the mixture was diluted with Et2O (40 mL) and 1:1 mixture of aqueous solution of saturated aqueous NaHCO3 (20 mL) and saturated aqueous Na2S2O3 (20 mL) was added. After 15 hours, the aqueous layer was separated and extracted with Et2O (2 x) and EtOAc (2 x). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo to afford S-bromo-isoxazole-S-carbaldehyde as a yellowish/orange solid. MS m/z 194.00 (M+ H2O); 195.97 (M+2).
