実験手順: A mixture of N-[3-(hydroxymethyl)phenyl]acetamide (10 g, 60.6 mmol) and MnO2 (7.8 g, 90 mmol) in toluene (250 mL) was refluxed for 29 hr, with addition of more MnO2 (0.7 g, 9 mmol) at 24 hr. The reaction was cooled, filtered through Celite and concentrated in vacuo to give N-(3-formylphenyl)acetamide (9.2 g, 75%). ES-MS (M+H)+=164. The reaction was cooled filtered through Celite concentrated in vacuo

実験手順: To a chilled suspension of 3-aminobenzyl alcohol (9.24 g, 75 mmol) in THF (50 mL) was added neat acetic anhydride (8.1 mL, 86 mmol). The reaction mixture was stirred cold for 1 hr, diluted with EtOAc, washed with aq. NaOH and brine, and concentrated in vacuo to give N-[3-(hydroxymethyl)phenyl]acetamide (10.5 g, 85%). washed with aq. NaOH and brine concentrated in vacuo

実験手順: Methanesulphonyl chloride (0.15 ml) was added to a stirred solution of 3-acetylaminobenzylalcohol (260 mg) and TEA (0.26 ml) in DCM (2 ml) at 0° C. The reaction was allowed to warm to room temperature and stirred for two hours. The mixture was diluted with EtOAc (20 mL) and MeOH (1 ml) and stirred for 5 minutes. The mixture was then washed with water (30 ml), organic layer was dried over sodium sulphate and solvent evaporated. The residue was columned on silica gel using DCM then ethyl acetate as eluant to give 3-acetylaminobenzylchloride (210 mg). 1H NMR (CDCl3) δ: 7.59 (s, 1H), 7.41 (d, 1H), 7.31 (t, 1H), 7.14 (d, 1H), 4.56 (s, 2H), 2.18 (s, 3H). stirred for 5 minutes The mixture was then washed with water (30 ml), organic layer was dried over sodium sulphate and solvent evaporated
