Procedure: A mixture of 3-(4-acetamidophenyl)propanal (96 mg, 0.50 mmol), methoxylamine hydrochloride (92 mg, 1.1 mmol), and pyridine (110 μL) in methanol (0.7 mL) is heated in a 70° C. oil bath for 18 hours and then allowed to cool to room temperature. Methanol (1 mL) is added and the mixture is cooled to 0° C. in an ice-water bath. Borane.pyridine complex (0.11 mL, 1.1 mmol) is added, followed by the dropwise addition of 10% aqueous hydrochloric acid. The mixture is allowed to warm to room temperature and then concentrated under reduced pressure. The residue is purified by reverse-phase HPLC to give N-[4-(3-methoxyamino-propyl)-phenyl]-acetamide. to cool to room temperature the mixture is cooled to 0° C. in an ice-water bath pyridine complex (0.11 mL, 1.1 mmol) is added to warm to room temperature concentrated under reduced pressure The residue is purified by reverse-phase HPLC

Procedure: To a suspension of N-[4-(3-Oxo-propyl)-phenyl]-acetamide (96 mg, 0.50 mmol), dimethylamine hydrochloride (82 mg, 1.0 mmol), and sodium acetate (66 mg, 0.80 mmol) in methanol (0.5 mL) is added sodium cyanoborohydride (47 mg, 0.75 mmol). Upon completion of the reaction, the solvent is evaporated under reduced pressure and the residue is partitioned between ethyl acetate and water. The aqueous phase is extracted with ethyl acetate. The combined extracts were concentrated to give N-[4-(3-dimethylamino-propyl)-phenyl]-acetamide (0.14 g, >100%).

Procedure: To a mixture of N-(4-Iodophenyl)acetamide (10.8 g, 42 mmol, 1.0 equiv) and DMF (50.0 ml) were added tetrabutylammonium chloride (11.7 g, 42 mmol, 1.0 equiv), NaHCO3 (8.7 g, 105 mmol), and allyl alcohol (4.2 ml, 63 mmol, 1.5 equiv) and the mixture was stirred for 10 min. To the resulting mixture PdCl2 (1.21 g, 9.6 mmol, 0.23 equiv) was added and the mixture was stirred under nitrogen for 45 h. The resulting mixture was extracted with EtOAc (3×100 ml). The combined extracts were washed with 5% HCl, brine, dried over MgSO4 and concentrated under vacuum. The residue was purified by column chromatography (EtOAc:hexane 70:30) to give 3-(4′-Acetamidophenyl)-1-propanal (1.92 g, 23.1%) which was used as such in the next step. the mixture was stirred under nitrogen for 45 h The resulting mixture was extracted with EtOAc (3×100 ml) The combined extracts were washed with 5% HCl, brine dried over MgSO4 concentrated under vacuum The residue was purified by column chromatography (EtOAc:hexane 70:30)
