The procedure described in Example 5(a) was repeated, but using 280 mg (0.728 mmole) of (2R, 4S, 5S)-5-(t-butoxycarbonyl)amino-6-cyclohexyl-4-hydroxy-2-methyl-N-propylhexanamide (prepared as described in Preparation 18) and 204 mg (0.75 mmole) of N-(t-butoxycarbonyl)-3-(4-thiazolyl)-L-alanine, to afford 306 mg of the title compound as colorless crystals, melting at 182°-184° C.
