Reaction Steps

To a mixture of 1.78 g (8.3 mmol) of ethyl-(5,5,8-trimethyl-5,6-dihydro-naphthalen-2-yl)-amine (Compound 166) and 0.55 g (3.9 mmol) of 6-fluoro-nicotinic acid was added a small amount of ether and toluene to help stirring. The resulting mixture was heated at 100-150° C. for 1 h. The mixture was cooled. The product was purified by flash chromatography (silica, 50% ethyl acetate in hexanes) followed by recrystallization using ethyl acetate:hexane (1:1) to give the title compound as white crystals (158 mg).
