A mixture of 6-(2-amino-4-methoxyphenyl)-5,6,7,8-tetrahydronaphthalen-2-ol (800 mg) and formic acid (8 ml) was refluxed overnight. The reaction mixture was diluted with a saturated aqueous solution of sodium bicarbonate, extracted with ethyl acetate, then washed with brine, dried over anhydrous magnesium sulfate, then the solvent was evaporated in vacuo. Synthesized from the resulting residue according to an analogous synthetic method to Example 337 described below, the title compound (730 mg) was obtained.
