Participants

Reaction Steps

To a solution of (S)-tert-butyl 1-(methylamino)-3-(4-methylcyclohexyl)-1-oxopropan-2-ylcarbamate (1.0075 g, 3.38 mmol, 1.0 equiv) in THF (40 mL) was added 7 mL (7 mmol, 2.1 equiv) of 1.0 M LiAlH4 in THF at 0° C. under N2. The mixture was stirred at rt for 19 h and then sodium sulfate decahydrate (6.45 g, 20 mmol) was added carefully to quench excess LiAlH4. The mixture was filtered and the solid was washed with ether. After the solvents were removed in vacuo, the crude (S)-tert-butyl 1-(methylamino)-3-(4-methylcyclohexyl)propan-2-ylcarbamate (1.04 g) was used in the next step without further purification. MS ESI +ve m/z 285 (M+H).
