A solution of the crude (RS)-4-bromo-2-(1-cyclopropyl-2-iodo-1-isocyanato-ethyl)-1-fluoro-benzene (6.40 g, 16 mmol) in tent-butanol (200 ml) was treated at 23° C. with triethylamine (2.16 ml, 16 mmol) and the mixture was stirred overnight at reflux. For the workup, the reaction mixture was evaporated at reduced pressure to yield the crude title compound as a yellow oil which was directly used in the next step. Mass (calculated) C12H11BrFNO2 [300.126]; (found) [M+H]+=300, [M+2-H]+=302.
