methyl 3-[4-(bromomethyl)phenyl]propanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4-Chloro-N-((R)-5,5-dimethyl-2-oxo-azepan-3-yl)-benzenesulfonamide was alkylated using 3-(4-bromomethyl-phenyl)-propionic acid methyl ester analogous to Example 2c to yield 3-(4-{[(4-chloro-benzenesulfonyl)-((R)-5,5-dimethyl-2-oxo-azepan-3-yl)-amino]-methyl}-phenyl)-propionic acid methyl ester: MS: m/e=507.6 (MH+).

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The title compound was prepared in analogy to Example 19, intermediate b, from 2-(4-chloro-2-methoxy-phenyl)-5,6-difluoro-1H-benzoimidazole (Example 19, intermediate c) and 3-(4-bromomethyl-phenyl)-propionic acid methyl ester (CAS Reg. No. 56607-18-2). Brown sticky solid (75%). MS (Turbo Spray): m/z=471.0 (M+H).

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
