Procedure
In analogy to example 74, step 5, from 3-(3-bromo-phenyl)-N-methoxy-N-methyl-3-o-tolyl-propionamide (example 98, step 4) and 3,5-dibromopyridine (CAS RN: [625-92-3]) using i-propylmagnesium bromide instead of n-butyllithium was prepared the title compound as a white solid, MS (ESI+): m/z=457.9738 ([M+H]+, 1Br).
