摘要
Racemic 6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline (FTHQ) was resolved by the N-phthaloyl derivative of the (R)-enantiomer. The enantiomeric mixture was very effectively enriched by recrystallisation from either the melt (working best for mixtures of relatively high starting enantiomeric purities) or from solution of its hydrochloride salt (giving good results when applied for mixtures of moderate to medium enantiomeric purities).
