Reaktionsschritte
80 μmol of 2,4-diaminophenol.2HCl and 80 μmol of 5-chloro-naphthalene-1-carboxylic acid were dissolved in 100 mg of PPA, and then, the mixed solution was stirred at a temperature of 180° C. for 3 to 4 hours. After completion of the reaction, the reaction solution was cooled, neutralized with 10% NaOH, and filtered by using distilled water for recrystallization in a slow manner, thereby obtaining 18.7 mg of 2-(5-chloronaphthalene-1-yl)benzo[d]oxazole-5-amine (Derivative #5) (yield: 79%).
