Reaction Steps
To a mixture of aldehyde from Step 3 (252 mg, 0.929 mmol) and THF (8 mL) under argon at 0° C., was added trifluoromethylsilane (132 mg, 0.929 mmol), followed by tetrabutylammonium fluoride (1M solution in THF, 50 mL). The reaction was warmed to 23° C. After 2 h at 23° C., the reaction was treated with 3N HCl (125 mL). After 4 h, the reaction was diluted with ether (75 mL), washed with brine (2×100 mL), and dried (MgSO4). Concentration in vacuo afforded a brown oil (214 mg, 67.4%) which was taken on to the next step without further purification: 1H NMR (CDCl3) δ2.63 (t, J=7 Hz), 2.97 (t, J=7 Hz), 4.68 (br s), 4.88 (q, J=6 Hz), 6.73-6.82 (m), 7.11-7.35 (m), 7.83-7.92 (m), 8.85 (br s). IR (neat) 3450-3050, 1667 cm−1. MS (EI) 341 (M+), 323, 209, 140. Anal. Calc'd. for C17H15NO2F4: C, 59.82; H, 4.43; N, 4.10. Found: C, 59.81; H, 4.57; N, 4.08.
