The same procedure as in Example 6 was repeated except that the molar ratio of 2-iodohexane to o-aminophenol was changed to 0.8, the 2-iodohexane was dropped over 4.5 h, and then the reaction mixture was stirred at room temperature for 0.5 h. As a result, it was confirmed that the rate of conversion of o-aminophenol was 71%, the selectivity to the N-monoalkylated compound was 86%, and the oxygen absorption initiation time as an index of determining an oxidation-inhibiting property thereof was 320 min.
