Reaction Conditions

Reaction Steps

Under nitrogen atmosphere, the acetic acid (1 mL) suspension of 7-methoxy-1,1-dimethyl-3,4-dihydro-1H-naphthalen-2-one (Compound A2, 101.0 mg, 0.495 mmol) and (3-fluoro-phenyl)-hydrazine hydrochloric acid salt (Compound V1, 96.5 mg, 0.593 mmol) was stirred at ambient temperature of 95° C. for 3.75 hr. After cooling to room temperature, the reaction mixture was added with water (1 mL) and hexane/ethyl acetate (15:1) (0.5 mL), and stirred at room temperature for 15 min. The solid was filtered, washed with hexane/ethyl acetate (15:1), and then dried under reduced pressure to obtain the title compound (beige powder, 72.7 mg, 50%).
