A procedure similar to that described in Example 2 was repeated, except that 100 mg (0.176 mmoles) of (2S, 4S, 5S)-5-[N-(t-butoxycarbonyl)-3-(4-thiazolyl)-L-alanyl]amino-6-cyclohexyl-4-hydroxy-2-(1-hydroxy-1-methylethyl)-N-ethylhexanamide [prepared as described in Example 14(a)], 50 mg (0.18 mmoles) of 2(R)-benzyl-3-(morpholinocarbonyl)propionic acid, 0.28 ml (2 mmoles) of triethylamine, and 0.029 ml (0.18 mmoles) of diethyl cyanophosphate were used, to obtain 41 mg of the title compound.
