Abstract
Described are processes for the manufacture of compounds containing a (S)-4,5-dihydro-1H-pyrazole ring. These processes include a chiral resolution step of an intermediate using selected chiral resolving agents. For example, the chiral resolving agents may be selected from (−)-quinine, (R)-phenethylamine, (S)-phenethylamine, (S)-1-naphthylethylamine, (R)-(−)-2-amino-3-methyl-1-butanol, (−)-cinchonidine, (−)-spartein, (R)-1-naphthylethylamine, D-arginine, L-lysine, (S)-(+)-2-pyrrolidinemethanol and (1R,2S)-(+)-cis-1-amino-2-indanol.
