Reaction Steps

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).
