반응 단계
Racemic ibuprofen (18.03 g, 87.4 mmol), N-octyl-D-glucamine (12.12 g, 41.3 mmol), triethylamine (4.4 g, 43.5 mmol), water (0.5 mL), and toluene (150 mL) were heated to 80° C., forming a clear solution. The solution was cooled to 25° C. over 2 1/2 hours, then cooled in an ice bath to 15° C. The resulting crystalline precipitate was recovered by filtration, washed with toluene, and dried to give (S)-ibuprofen N-octyl-D-glucamine salt (17.2 g, 78.8% yield, 94.8% ee).
