Reaction Steps

A solution of 3,5-dichloro-4-methoxybenzaldehyde methoxime (10.7 g, 46 mmol) in freshly distilled tetrahydrofuran (THF) (60 ml) was cooled to 0° and stirred while 47 ml of 0.98M borane in THF was added. The resulting mixture was heated under reflux for 2 hours, cooled, and water (20 ml) added followed by 20% aqueous sodium hydroxide (20 ml). The mixture was heated under reflux for 2 hours, cooled and extracted twice with diethyl ether. The organic layer was extracted with 3N HCl, the aqueous layer made basic with 50% aqueous sodium hydroxide and the product was extracted into diethyl ether. The organic extracts were dried (Na2SO4) and concentrated to give 6.11 g (65%) of the title compound as a pale yellow oil.
