Reaction Conditions

Reaction Steps

To a solution of (5)-tert-butyl 1-((4-methoxyphenyl)(methyl)amino)-1-oxo-3-(3-vinylphenyl)propan-2-ylcarbamate (2.9 g, 7.06 mmol) and thioacetic acid (5 ml) in toluene (30 ml), was added azobisisobutyronitrile, (3.2 ml, 0.2M in toluene) dropwise. The solution was degassed for 30 minutes by purging with nitrogen. After purging was complete, the reaction was heated at 100° C. for 2 hours. The reaction was cooled to room temperature and then diluted with EtOAc (100 ml). The organics were washed with sodium bicarbonate (3×). The organic layer was dried with Na2SO4, filtered and concentrated. The crude product was introduced to a silica gel loading column and purified by column chromatography (20-50% EtOAc/hexanes) to provide the desired product (2.8 g, 5.74 mmol), 81.4%. MS (m/z) 487 [M+H]+.
