Reaction Conditions:
with trifluoroacetyl peroxide in dichloromethane at -5 - 5; for 4 h;
Steps:
6
Add a peroxytrifluoroacetic acid solution to the reaction vessel, lower the temperature to -5 to 5 ° C, add 1-aminonaphthalene 859.14g (6mol), keep the temperature at -5 to 5 ° C, and stir the reaction for 4 hours. After the reaction, add 2L of water and stir , And allowed to stand and separate. The organic layer was washed with 2L saturated sodium bisulfite solution, 2L saturated sodium bicarbonate solution, and water to pH 7-8, and the solvent was distilled off under reduced pressure.With dichloromethane and methanol (dichloromethane and methanol volume ratio of 1: 2)The solution was recrystallized to obtain 935.1 g (yield 90%) of as a yellow solid.
