Procedure

A mixture of [3-bromo-1-(4-nitro-benzyl)-2-oxo-propyl]-carbamic acid tert-butyl ester, 51, (1.62 g, 4.17 mmol) and benzothioamide (0.630 g, 4.59 mmol), in CH3CN (5 mL) is refluxed for 24 hours. The reaction mixture is cooled to room temperature and diethyl ether (50 mL) is added to the solution and the precipitate that forms is collected by filtration. The solid is dried under vacuum to afford 1.059 g (63%) of the desired product. ESI+ MS 326 (M+1).
