실험 절차

A mixture of (trans)-β-Nitrostyrene (50.0 g, 0.335 mol), tris(triphenylphosphine)rhodium(I) chloride (10.7 g) and benzene (500 mL) at 50° C. was shaken under hydrogen at 50 psi for 14 hours and allowed to cool. The solution was rotoevaporated, suspended in petroleum ether-ether (9:1), and gravity filtered through a plug of fluorisil (80 g)/silica gel (300 g). The filtrate was rotoevaporated to a pale yellow oil; yield (49.5 g, 98%).
