실험 절차
93 g of 4-(N-octylamino)-2,2,6,6-tetramethylpiperidine and 33 g of tetrabutyl orthotitanate in 175 ml of ethyl formate were refluxed for 10.5 hours. Working up as in Example 2 gave 4-(N-octyl-N-formylamino)-2,2,6,6-tetramethylpiperidine as a colorless oil of boiling point 145°-147° C./0.5 mmHg
