A procedure similar to that described in Example 2 was repeated, except that 100 mg (0.19 mmoles) of (2S, 4S, 5S)-5-[N-(t-butoxycarbonyl)-3-(4-thiazolyl)-L-alanyl]amino-4-hydroxy-2-(1-hydroxy-1-methylethyl)-7-methyl-N-methyloctanamide [prepared as described in Example 16(a)], 62 mg (0.21 mmoles) of N-morpholinoacetyl-L-phenylalanine, 0.03 ml (0.20 mmoles) of diethyl cyanophosphate, and 0.08 ml (0.57 mmoles) of triethylamine were used, to obtain 104 mg (yield 78%) of the title compound as a white amorphous substance.
