실험 절차
1.1 g of potassium hydroxide (KOH) and 5.8 g of triphenyl phosphine (Ph3P) were added to a solution of 1-azidomethyl-3-bromo-2-methoxy-benzene 7 in 100 mL of THF and 10 mL of water. The mixture was stirred overnight at room temperature. The mixture was quenched with aqueous concentrated hydrochloride. After standard acid/base aqueous work up, 3.9 g of crude 3-bromo-2-methoxy-benzylamine 8 was obtained (after two steps).
