Reaction Steps

To a solution of 2-(6-methoxy-1,2-benzisoxazol-3-yl)-3-(4-methoxyphenyl)propanenitrile (1.5 g, 4.9 mmoles) in CH2Cl2 (100 ml) under N2, was added BBr3 1M in CH2Cl2 (4 eq, 20 ml). The mixture was refluxed for 2 h, poured into water and extracted with EtOAc, dried over Na2SO4, filtered and concentrated under vacuum to give the crude product. Purification by flash chromatography (CH2Cl2/MeOH 98/2) and crystallisation from EtOH yielded the expected crystals (850 mg, 62%). mp 214° C.
