Morpholine → HCID 68619808, compound

Participants

Reaction Steps

To a stirred solution of (R)-tert-butoxycarbonylamino-[4-(2-methanesulfonyloxy-ethoxy)-phenyl]-acetic acid methyl ester (50 mg, 0.12 mmol) in ethanol (1 mL) was added morpholine (0.043 mL, 0.49 mmol) at room temperature. The reaction mixture was refluxed for 1 hour. The solvent was evaporated and the crude product was purified by chromatography over silica gel eluted with 1:1 v/v hexanes/ethyl acetate to give (R)-tert-butoxycarbonylamino-[4-(2-morpholin-4-yl-ethoxy)-phenyl]-acetic acid methyl ester (45 mg, 92% yield) as a colorless oil.
