Procedure
Carbonyldiimidazole (0.2 g) was added to a solution of the above amine in THF (10 mL). The resulting mixture was stirred at RT overnight, silica gel was added, then the solvents were removed under reduced pressure and purified via column chromatography, elution with 5% MeOH/DCM, to yield the titled product (28 mg), MH+=403, 1H NMR (CDCl3) δ 10.6 (s, 1H), 8.9 (s, 1H), 8.3 (s, 1H), 7.8 (m, 2H), 7.3 (m, 2H), 7.0 (m, 1H), 6.7 (m, 1H), 5.9 (dd, 1H), 4.7 (m, 1H), 4.4 (t, 1H), 2.7 (m, 1H), 2.3 (m, 1H) ppm, 19F NMR δ −135.7 (m). Chiral HPLC—no evidence of other enantiomer, Method; Chiralcel™ OD-H (0.46×25 cm analytical column, Daicel Chemical Industries) isocratic 15% (0.05% TFA/EtOH) 85% (0.05% TFA/Hex), Rt=19.5 min (R)-enantiomer, Rt=22.4 min (S)-enantiomer.
