Reaction Steps

A mixture of ethyl (2RS,3RS)-3-(2,3-dihydro-4H-1,4-benzoxazin-4-yl)-2-hydroxy-3-phenylpropanoate (283 mg, 0.864 mmol) and ethanolic methylamine solution (5 mL, 33% in ethanol) was stirred at 70° C. in a sealed tube for 5 hours. After cooling, all volatiles were removed under reduced pressure. The resulting yellow solid was purified via Biotage Horizon (FLASH 12 S, silica, 20%, 35%, 50% EtOAc/hexane) to yield 235 mg (87%) (2RS,3RS)-3-(2,3-dihydro-4H-1,4-benzoxazin-4-yl)-2-hydroxy-N-methyl-3 phenylpropanamide as a white solid. MS (ESI) m/z 311.0 ([M−H]−).
