The 1-phenyl-2-trimethylsilyl-2,3-dihydro-1H-2,1-benzazaphosphole-1-oxide was dissolved in 50 ml. of methanol and heated at reflux for 4 hours. After stirring for 16 hours at 26° C., the resulting solution was concentrated in vacuo and the residue was crystallized from ethyl acetate to yield 1-phenyl-2,3-dihydro-1H-2,1-benzazaphosphole-1-oxide (9.0 g, 33% yield) as a white solid having a melting point of 177°-180° C. and the following analysis:
