Reaction Steps

To a stirred solution of tert-butyl 6-[(2R,6S)-2,6-dimethylmorpholin-4-yl]-7-fluoro-5-formyl-2,3-dihydro-1,2-benzisoxazol-3-yl carbonate (Intermediate 533, 0.5 g, 1.2 mmol) in methanol (5 ml) was added 5 ml of 5% aqueous HCl before heating at 75° C. for 2 hours. The reaction mixture was quenched with 10% aqueous sodium bicarbonate solution and extracted with EtOAc. The organic layer were washed with water, dried (sodium sulfate), and concentrated. The residue purified over a silica gel flash column (elution with 50-70% EtOAc in hexanes) to give product.
