Conditions

Temperature: 80 °C

Procedure

10% sodium hydroxide aqueous solution (7.21 g) was added to a solution containing 3-(2-hydroxyphenyl)-N-(3-morpholinopropyl)propanamide (2.60 g) obtained in Example 5(1) in dimethylsulfoxide (36 ml). The mixture was heated up to 80° C. and 1-bromooctadecane (2.97 g) was added thereto. After being stirred for 2.5 hours at 80° C., the reaction mixture, with water added thereto, was neutralized with 1N hydrochloric acid. The deposited solid was corrected by filtration and washed with water. This solid was purified by silica gel column chromatography (silica gel 100 g, chloroform:methanol=60:1 to 30:1), thereby yielding the entitled compound (1.99 g) as white solid.
