Methanol → (2S,3S)-N-[(1S,2S)-2-hydroxycyclohexane-1-yl]-3-azido-2-hydroxyheptanamide

Participants

Reaction Steps

30 ml of a methanol suspension containing 1.64 g (7 mmol) of (2S)-trans-N-[(1S,2S)-2-hydroxycyclohexane-1-yl]-3-butyloxiranecarboxamide, 910 mg (14 mmol) of sodium azide and 868 mg (7.2 mmol) of anhydrous magnesium sulfate was refluxed for 5 hours. After the temperature of the reaction mixture was returned to room temperature, the reaction mixture was poured into 300 ml of water and the resulting mixture was stirred for 2 hours. The resulting crystals were collected by filtration and washed with water, and dried to obtain 1.45 g (Yield: 73%) of the title compound.
