Reaction Steps

A vial was charged with morpholine (0.062 mL, 0.706 mmol), (S)-2-amino-5′-fluoro-2′-(3-methoxyphenylamino)-5H-spiro[oxazole-4,9′-xanthene]-7′-yl trifluoromethanesulfonate (127 mg, 0.235 mmol), Pd2 dba3 (10.78 mg, 0.012 mmol), (8.43 mg, 0.028 mmol). The tube was flushed with argon and LiHMDS (1M in THF) (0.942 mL, 0.942 mmol) was added and the vial sealed and heated at 110° C. in microwave reactor for 1 hr. The mixture was quenched with 1 ml of water, diluted with EtOAc, and loaded onto 2 g SCX-2 column. The column was washed with EtOAc and MeOH. The material was flushed from the column using 2M ammonia in MeOH. The derived solution was purified by silica gel chromatography to afford (S)-4′-fluoro-N7′-(3-methoxyphenyl)-2′-morpholino-5H-spiro[oxazole-4,9′-xanthene]-2,7′-diamine MS m/z=477.0 [M+H].
