Reaction Steps

To a solution of 5-methoxy-3,4-dihydronaphthalen-1(2H)-one (200 mg, 1.14 mmol) and hydroxylamine methyl ether hydrochloride (284 mg, 3.40 mmol) in MeOH (5 mL) was added sodium acetate (279 mg, 3.40 mmol). The reaction mixture was heated at 60° C. for 1 h, cooled and partitioned between H2O and EtOAc. The organic layer was separated, dried over Na2SO4, filtered, and concentrated in vacuo to give Intermediate 34A (0.20 g, 1.1 mmol, 92% yield) which was used directly in the next step without further purification. LCMS=1.78 min [M+1]=192.1 (Method B).
