26% | A solution of n-BuLi (11.76mL, 18.82mmol, 1.6M in hexane) was added dropwise to a cold (-78C) stirred solution of 6-bromo-2-methoxynaphthalene (4.24g, 17.90mmol) in anhydrous THF (75mL). After 30min <strong>[116332-54-8]4-fluoro-N-methoxy-N-methylbenzamide</strong> 7a (1.64g, 8.96mmol) in anhydrous THF (15mL) was added slowly over 10min. The resulting mixture was stirred for 2h whilst warming to room temperature. Water (100mL) was added and the organic layer was separated. The aqueous layer was extracted with ethyl acetate (3×50mL), and the combined organic extracts were dried over anhydrous Na2SO4. Removal of the solvent under vacuum afforded the crude 6-(4-fluorobenzoyl)-2-methoxynaphthalene 18a as an off-white solid in 26% yield after crystallisation from ethanol, mp 113-115C; numax 660, 893, 918, 960, 1151, 1225, 1388, 1504, 1619, 1648, 2921cm-1; deltaH 3.97 (3H, s, OMe), 7.19 (4H, m, Ar-H, 1-H), 7.81 (1H, d, J=8.7Hz, 4-H), 7.82 (1H, d, J=8.5Hz, 8-H), 7.88 (3H, m, Ar-H), 8.18 (1H, d, J=1.2Hz, 5-H). Found [M+H]+=281.0973. C18H13FO2 requires [M+H]+=281.0972. |
