Reaktionsschritte

A mixture of 1-bromo-1-methylcyclohexane (7.200 g, 3.0 equiv), tributyltin hydride (8 mL, 2.2 equiv), methyl 2-(benzyloxycarbonylamino)acrylate (3.120 g, 13.26 mmol, 1.0 equiv), and 2,2′-azobisisobutyronitrile (0.370 g, 0.17 equiv) in benzene (30 mL) was heated at 100° C. for 6 h. After the reaction mixture was evaporated under reduced pressure, the crude methyl 2-(benzyloxycarbonylamino)-3-(1-methylcyclohexyl)propanoate was used directly in the next step without further purification. MS ESI +ve m/z 356 (M+Na).
