실험 절차

The procedure of Example 1 was employed utilizing N-(3-methylphenyl)-N-benzylamine and isopropyl phosphonic dichloride. The crude product produced as a result of the chromatographic separation was distilled at 150° C. and 0.8 mm to yield a pale yellow glass. The yellow glass was crystallized from methylcyclohexane to yield 1-isopropyl-2-(3-methylphenyl)-2,3-dihydro-1H-2,1-benzazaphosphole-1-oxide (3.5 g, 20% yield) as a white crystalline solid having a melting point of 112°-113° C. and the following analysis:
