Participants

Reaction Steps

A 23 g. portion of α-chlorobenzaldoxime, prepared as in Example 1 above, was combined with 17 g. of crotylisothiocyanate in 300 ml. of diethyl ether. The solution was cooled to 15° and 40 ml. of triethylamine in 100 ml. of tetrahydrofuran was added dropwise. The mixture was stirred for 24 hours at 15°, and was then filtered. The filtrate was washed with water, and evaporated to dryness. The residue was dissolved in chloroform, and chromatographed over a column (2.5 cm. diameter by 8 meters long) of polystyrene gel beads. The eluate was evaporated to dryness, and the residue was recrystallized from diisopropyl etherhexane. The product was identified as 10 g. of 5-(2-isothiocyanatoethyl)-3-phenyl-2-isoxazoline, m.p. 54°-56°. The microanalytical results were as follows:
