Reaction Steps

To a mixture of (RS)-2-(5-(1-hydroxy-ethyl)-isoxazol-3-yl)-pyridine (0.9 gm), and triphenylphosphene (1.77 gm) in dichloromethane (20 ml) was added carbontetrabromide (6 gm) at 0° C. The reaction mixture was stirred at 30° C. over a period of 2.5 h. The reaction was monitored by TLC. The reaction was quenched by addition of water and layers were separated. Combined organic extract was washed with brine and evaporated under vacuum to provide the 1.7 gm crude mass which was purified by using silica gel column chromatography to provide title compound in 0.8 gm quantity (65%).
