실험 절차

A solution of 1.0 g of (2-methylphenyl)diphenylphosphine in 30 ml of ether was treated with 4 ml of 1M ethyl carbonazidate in ether. The mixture was allowed to stand 48 hours, then repeatedly concentrated and finally treated with fresh ether and refrigerated, giving 930 mg of the desired compound, mp 113°-114° C.
