o-Hydroxybenzaldehyde (0.20 mole) was treated with aniline with vigorous stirring in a 1 liter Erlenmeyer Flask. After 15 min., 33 cc of 95% ethanol was added and the reaction mixture was stirred vigorously for an additional 5 min. The reaction mixture was left standing at room temperature for 10 min., then it was placed in an ice-bath for 0.5 hour. The crystals which formed were collected, washed with 95% ethanol, and air dried. Recrystallization from 85% ethanol yielded N-(o-hydroxybenzylidene)aniline. m.p. 47°-49° C.
