Reaction Steps

tert-Butyl [(R)-1-[[(1S,2R,3S)-1-(cyclohexylmethyl)-3-cyclopropyl-2,3-dihydroxypropyl]carbamoyl]-2-(methylthio)ethyl]carbamate was obtained as an amorphous solid, MS: 445 (M+H)+, by condensing (R)-Boc-(S-methyl)cysteine (J. Chem. Soc. C 1967, 2632) and (1S,2R,3S)-3-amino-4-cyclohexyl-1-cyclopropyl-1,2-butanediol in an analogous manner to that described in Example 1g). Subsequent cleavage of the Boc protecting group using hydrochloric acid in methanol yielded (R)-2-amino-N-[(1S,2R,3S)-1-(cyclohexylmethyl)-3-cyclopropyl-2,3-dihydroxypropyl]-3-(methylthio)propionamide.
