実験手順
The product of Example 3F (28 mg, 52.4 μmol) was dissolved in 0.5 mL acetonitrile in a 5 mL flask and to this was added a solution of potassium fluoride (4.5 mg, 78.6 μmol) and Kryptofix 222 (29.6 mg, 78.6 μmol) in 0.5 mL acetonitrile. The above solution was then immersed in a oil bath preheated to 90° C. The reaction was allowed to stir for 90 minutes after which all the volatiles were removed under reduced pressure and the crude mixture purified by preparative thin layer chromatography to obtain 13 mg (65%) of pure desired compound. 1H (CDCl3) δ (ppm): 7.72 (s, 1H), 7.3 (d, 2H), 6.9 (d, 2H), 5.23 (s, 2H), 4.57-4.59 (m, 2H), 4.4 (m, 4H), 1.74 (m, 2H), 1.6 (s, 9H), 1.0 (t, 3H). 13C (CDCl3) δ (ppm): 159, 158.7, 153.7, 129, 127.5, 125.2, 118.3, 116.4, 83.85 (d, 1JCF=172.2), 78, 71.1, 66.3, 27.8, 23.2, 9.48. 19F (CDCl3, CFCl3 as internal standard) δ (ppm): −228 (d of t, J=−19, −60 Hz)
