Reaction Steps

To 6D (450 mg, 1.5 mmol) in CH2Cl2 (5 mL) at 0° C. was added triethylamine (0.42 mL, 3.0 mmol) followed by mesyl chloride (0.14 mL, 1.8 mmol). After stirring at rt overnight, the reaction was concentrated and purified via silica gel chromatography (0-25% ethyl acetate/hexanes) to provide 6E (268 mg, 56%). 1H NMR (400 MHz, CD3OD) δ ppm 3.81 (s, 3H) 3.87 (s, 3H) 5.19 (m, 2H) 5.36 (s, 1H) 6.81 (d, J=8.35 Hz, 1H) 6.93-7.07 (m, 2H) 7.20-7.42 (m, 5H).
