Reaction Steps

A solution of MeMgI (1.47 mmol) in Et2O (3.0 M, 0.49 mL) was added dropwise over 2 min to a stirred mixture of the aldehyde from Step 1 and THF (10 mL) at 0° C. under N2. The reaction mixture was stirred for 15 min and then quenched by the addition of NH4Cl solution (15 mL). The organics were extracted into EtOAc (40 mL), concentrated under reduced pressure, and purified by column chromatography on silica, eluting with 80% EtOAc/iso-hexane to yield the alcohol (121 mg, 58%). 1H NMR (CDCl3, 400 MHz) δ 7.60-7.45 (3H, m), 7.35 (1H, d, J=7.6 Hz), 6.23 (1H, s), 5.08 (1H, s), 4.98 (1H, q, J=6.5 Hz), 4.15-4.07 (2H, m), 3.53-3.42 (2H, m), 1.82 (6H, s), 1.57 (3H, d, J=6.5 Hz), 1.39 (3H, t, J=7.2 Hz). MS (ES+) C18H24F3N3O3S requires: 419, found: 420 (M+H+, 100%).
