実験手順

BCl3 (1M sol. in CH2Cl2, 3.87 ml, 3.87 mmol) was added dropwise to a solution of the crude 5-(2,4-Bis-benzyloxy-5-chloro-phenyl)-4-(4-morpholin-4-ylmethyl-phenyl)-isoxazole-3-carboxylic acid ethylamide (810 mg, ˜1.29 mmol) in CH2Cl2 (30 ml) at 0° C. The reaction was then allowed to reach RT. Saturated aqueous NaHCO3 (40 ml) was then added slowly and the resultant mixture concentrated in vacuo. This was then partitioned between EtOAc (3×50 ml) and water (50 ml). The combined, dried (Na2SO4) organics were evaporated in vacuo. Flash chromatography eluting with CH2Cl2-10% MeOH/1% NH3/CH2Cl2 afforded 5-(5-Chloro-2,4-dihydroxy-phenyl)-4-(4-morpholin-4-ylmethyl-phenyl)-isoxazole-3-carboxylic acid ethylamide (380 mg, 64% over 2 steps) as a yellow foam, LC/MS: RT=1.751 min. 458.2 (MH+).
