Reaction Steps

[2S-[2α,4α[(R*,R*)]]]-2-[4-[4-[4-[4-[[2-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-4,5-dihydro-5-oxo-1H-1,2,4-triazol-1-yl]-1-methylpropyl β-alanine (0.0028 mol) was dissolved in warm ethanol (25 ml). (−)-(S)-hydroxybutanedioic acid (0.0061 mol) was added and the mixture was parboiled until complete dissolution. The resulting clear solution was allowed to cool to room temperature and the solvent was evaporated. The residue was stirred in 2-propanone, filtered off, then dried, yielding 1.53 g (53%) [2S-[2α,4α-[(R*,R*)]]]-2-[4-[4-[4-[4-[[2-(2,4-difluorophenyl)-2-(1H-1,2,4-triazol-1-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-1-piperazinyl]phenyl]-4,5-dihydro-5-oxo-1H-1,2,4-triazol-1-yl]-1-methylpropyl β-alanine (S)-hydroxybutanedioate(1:2) monohydrate (compound 12).
