N-amino-morpholine hydrochloride → 4-[(1R,2E,4R,5S,8S,12R)-4-methyl-2-morpholin-4-ylimino-6-oxo-9,13-dioxa-7-azatetracyclo[6.3.1.11,4.05,12]tridecan-7-yl]-2-(trifluoromethyl)benzonitrile

온도

50 °C

To a stirring solution of Example 3 (85 mg, 0.216 mmol) in pyridine (2 mL) was added. N-aminomorpholine hydrochloride (0.287 mmol, 1.5 eq). The mixture was stirred at 50° C. for 1 h. The reaction was judged completed by LCMS. The reaction mixture was cooled to room temperature. It was then diluted with EtOAc (6 ml) and extracted with 1N HCl (2×10 ml). The ethyl acetate layer was then washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude was purified on Isco (12 g column) 0-5% MeOH-DCM to give Example 92 (59 mg, 58%, 0.133 mmol).
