Reaction Conditions

Reaction Steps

130 mg of 2,6-dichloro-4-(cyclopropylmethoxy)pyridine, mg of (S)-(−)-1-(4-fluorophenyl)ethylamine, 36 mg 2-(di-t-butylphosphino)biphenyl, 144 mg of sodium t-butoxide and 14 mg of palladium acetate were added in turn to 2 ml of degassed toluene, and the mixture was stirred at 80° C. for 15 minutes under argon atmosphere. The reaction solution was diluted with ethyl acetate. The solution was washed in turn with water and brine and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 122 mg of the objective compound as colorless oil.
