Morpholine → HCID 10989798, compound

Participants

Reaction Steps

To a stirred mixture of N-tert-butoxycarbonyl-1-bromo-2-(S)-amino-4-methylpentane 1.76 g, 6.3 mmol) and triethylamine (0.96 ml, 6.9 mmol) in THF (50 ml) at room temperature was added morpholine (0.60 ml, 6.9 mmol). The mixture was stirred overnight and the solvent removed under reduced pressure. The residue was partitioned between saturated aqueous ammonium chloride (50 ml) and ethyl acetate (2×100 ml). The crude N-tert-butoxycarbonyl-1-morpholino-2-(S)-amino-4-methylpentane was then used directly in the next step.
