Procedure

7-Methoxy-8-nitro-2,3,4,5-tetrahydro-1H-benzo[d]azepine (215 mg, 0.967 mmol) was placed into a sealable vial, suspended in Acetonitrile (10 mL) then (S)-2-Trifluoromethyl-oxirane (130 uL, 1.5 mmol) was added, followed by Macroporous carbonate resin (3.16 mmol/g loading; 0.810 g, 2.56 mmol). The reaction was stirred at room temperature for 24 h, filtered and concentrated in vacuo to afford (S)-1,1,1-Trifluoro-3-(7-methoxy-8-nitro-1,2,4,5-tetrahydro-benzo[d]azepin-3-yl)-propan-2-ol as an orange oil (316 mg, 97%), which was used without further purification. 1H-NMR (CDCl3, 400 MHz) δ 7.67 (s, 1H), 6.83 (s, 1H), 4.05 (m, 1H), 3.95 (s, 3H), 2.6-3.0 (m, 10H); 19F-NMR (CDCl3, 376 MHz) δ−78.7 (s).
