Procedure:
In a dried flask under an inert atmosphere, 50 mg (0.18 mmol) of 8-(3-fluoro-benzyloxy)-1,3-dihydro-benzo[d]azepin-2-one were dissolved in 3 ml of dichloromethane, and the solution cooled to 0° C. Thereupon, 21 mg (0.21 mmol) triethylamine were added and stirring continued at 0° C. Finally, 18 μl (0.2 mmol) of methoxyacetic acid chloride were added. The reaction mixture was left to warm to RT and stirring continued for 18 h. For the working-up, the reaction mixture was evaporated under reduced pressure. For purification, the crude material obtained was directly transferred on a column and chromatographed on silica gel using a 99:1-mixture of dichloromethane and methanol as the eluent. There were obtained 15 mg (24% of theory) of 8-(3-fluoro-benzyloxy)-3-methoxyacetyl-1,3-dihydro-benzo[d]azepin-2-one as a white powder; MS: m/e=356 (M+H)+.

Procedure:
Acetic acid was added to a solution of methylamine (0.45 mL, 5.30 mmol, 40% in water) in tetrahydrofuran (8 mL) to adjust the pH to 6. A solution of (2-formyl-4-phenyl-pyrrol-1-yl)-acetic acid ethyl ester (680 mg, 2.65 mmol) in tetrahydrofuran (4 mL) was added and the reaction mixture stirred at ambient temperature for 45 min.
