Reaction Steps

(2-Amino-6-chlorophenyl)methanol (16 g, 101 mmol), 5,7-dimethyl-3,4-dihydronaphthalen-1(2H)-one (20.0 g, 111 mmol), RuCl2(PPh3)3 (0.971 g, 1.01 mmol), and KOH (5.7 g, 101 mmol) were refluxed in 200 mL of toluene for 12 h. Water was collected from the reaction using a Dean-stark trap. The reaction mixture was allowed to cool to room temperature and filtered through a silica gel plug and eluted with dichloromethane. The product was washed by methanol and recrystallized from hexane to obtain ˜20 gram of the desired product which was confirmed by GC-MS.
