実験手順

To a suspension of 4-amino-2-(2,6-dioxo(3-piperidyl))isoindoline-1,3-dione (0.55 g, 2 mmol) in THF (30 ml) was added 3-trifluoromethylbenzoyl chloride (0.60 ml, 4 mmol). The mixture was heated to reflux for 18 hours. The reaction was cooled to room temperature, methanol (2 ml) was added, and the mixture stirred for 1 hour. The solvent was evaporated in vacuo leaving a solid that was slurried in diethyl ether (20 ml) and filtered to give 0.41 g (46%) of product as an off-white solid: mp 257–259° C.; 1H NMR (DMSO-d6) d 10.86 (s, 1H), 10.45 (s, 1H), 8.50 (d, J=8.5 Hz, 1H), 8.24–8.25 (m, 2H), 8.02–7.82 (m, 3H), 7.69 (d, J=7.3 Hz, 1H), 5.14 (dd, J=5.7 and 12.8 Hz, 1H), 2.95–2.82 (m, 1H), 2.67–2.48 (m, 2H), 2.14–2.07 (m, 1H); 13C NMR (DMSO-d6) d 171.75, 168.80, 167.31, 166.06, 163.43, 135.80, 135.60, 134.28, 131.16, 130.71, 129.75, 128.35, 128.29, 126.63, 123.59, 123.52, 118.65, 118.55, 48.84, 30.51, 21.62; Anal. Calcd. For C21H14F3N3O5: C, 56.64; H, 3.17; N, 9.44. Found: C, 56.48; H, 3.15; N, 9.41.
