Procedure
Trimethylamine is bubbled into a solution of the diester product from part (a) (483 mg., 0.86 mmole) in acetone (6 ml.) according to the procedure of Example 4 part (f) to yield 432 mg. of 1-[(S)-2-[[[1-[[(S)-2-[[(1,1-dimethylethoxycarbonyl]amino]-1-oxohexyl]amino]pentyl]hydroxyphosphinyl]oxyl]-1-oxopropyl]-L-proline, ethyl ester (isomer B). TLC (silica gel; isopropanol:ammonia:water, 7:2:1) Rf =0.60.
