7-Methoxy-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid → HCID 39098232, compound

Participants

Reaction Steps

7-Methoxy-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid (5.0 g) and (S)-(−)-1-phenethylamine (3.2 mL) were dissolved in methanol (50 mL), and the solvent was evaporated under reduced pressure to give crude crystals (7.33 g). This was recrystallized from a mixed solvent of methanol and isopropyl ether. The obtained crystals were partitioned between ethyl acetate and 1 mol/L-hydrochloric acid. The organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give (S)-7-methoxy-1,2,3,4-tetrahydronaphthalene-1-carboxylic acid (0.96 g).
