Procedure
In an analogous manner to that described in Example 16, by reacting t-butyl (4S,5R)-4-(cyclohexylmethyl)-5-[(R or S)-hydroxy-[(R or S)-tetrahydro-2-furyl]-methyl]-2,2-dimethyl-3-oxazolidinecarboxylate with N-[(S)-α-[(t-butylsulphonyl)methyl]hydrocinnamoyl]-3-(2,4-dinitrophenyl)-L-histidine there is obtained (S)-α-[(S)-α-[(t-butylsulphonyl)methyl]hydrocinnamamido]-N-[(1S,2R,3R or S)-1-(cyclohexylmethyl)-2,3-dihydroxy-3[(R or S)-tetrahydro-2-furyl]propyl]imidazole-4-propionamide in the form of a yellow amorphous powder, MS: 827 (M+H)+. The cleavage of the dinitrophenyl group with thiolactic acid is effected in an analogous manner to Example 13 and yields (S)-α-[(S)-α-[(t-butylsulphonyl)methyl]hydrocinnamamido]-N-[(1S,2R,3R or S)-1-(cyclohexylmethyl -2,3-dihydroxy-3-[(R or S)-tetrahydro-2-furyl]propyl]imidazole-4-propionamide as a pale yellow amorphous solid, MS: 661 (M+H)+.
