85 °C

In a 50 ml-three-necked flask, 0.40 g (2.77 mM) of heptanohydrazide, 1.05 g (3.03 mM) of 6-decyloxy-2-naphthoyl chloride and 20 ml of dioxane were placed and heated to about 85° C. under stirring. To the mixture, 1.05 ml (13.0 mM) of pyridine was added, followed by heating to 90°-92° C. and stirring for 40 minutes at 90°-92° C. After the reaction, the reaction mixture was cooled and poured into 150 ml of iced water to precipitate a crystal. The crystal was recovered by filtration, followed by washing with water and further washing with acetone to obtain 1.21 g of N-heptanoyl-N'-(6-decyloxy-2-naphthoyl)hydrazine (Yield: 96.0%). ##STR28##
