Reaction Steps
To a suspension of (E)-1-chloro-4-(4-(2-nitrovinyl)phenoxy)-2-(trifluoromethyl)benzene (13 g, 43.2 mmol) and silica gel (120 g, 100-200 Mesh) in i-PrOH (155 mL) and CHCl3 (465 mL), was added NaBH4 (13.65 g, 361 mmol) portionwise. The reaction mixture was stirred overnight at rt, filtered, and washed with DCM (1 L). The organic phase was washed with sat. NaHCO3 (200 mL), then brine, and dried over anhydrous Na2SO4 and concentrated to afford the title compound as a brown liquid (26 g, 50% yield).
