Versuchsvorschrift

A mixture of 4-benzyloxy-2-iodo-5-methoxybenzaldehyde (reference example 1-1) (12.2 g), hydroxylamine hydrochloride (2.54 g), sodium acetate (6 g) and ethanol (170 mL) was stirred at 70° C. for 1.5 hours. The mixture was concentrated under reduced pressure. Water was added to the residue, and the mixture was stirred at room temperature for 30 minutes. The solid was collected by filtration to give the title compound (12.8 g).
