Reaction Steps

A suspension of 10% palladium on carbon (38.9 mg, 0.037 mmol) in a solution of 2-isopropoxy-4-[(2-phenyl-1,3-dioxan-5-yl)oxy]phenyl benzoate (158.7 mg, 0.365 mmol) in EtOAc (3.65 mL) was stirred under H2 (double balloon pressure) at 25° C. for 4 days. The reaction mixture was filtered through a plug of Celite and the filtrate was concentrated in vacuo to afford the crude product. This was purified by flash chromatography (Biotage Horizon, 25M, Si, ˜20 mL/min, 100% hexanes for 144 mL, gradient to 100% EtOAc over 2394 mL) to afford 4-[2-hydroxy-1-(hydroxymethyl)ethoxy]-2-isopropoxyphenyl benzoate, as a colorless solid. Rf=0.17 (50% EtOAc in hexanes). LCMS calc.=347.15; found=347.06 (M+H)+. 1H NMR (500 MHz, CHCl3): δ 8.18 (d, J=7.8 Hz, 2 H); 7.61 (t, J=7.5 Hz, 1 H); 7.49 (t, J=7.7 Hz, 2 H); 7.03 (d, J=8.7 Hz, 1 H); 6.68 (d, J=2.7 Hz, 1 H); 6.56 (dd, J=8.8, 2.7 Hz, 1 H); 4.45 (p, J=6.1 Hz, 1 H); 4.34 (p, J=4.8 Hz, 1 H); 3.89-3.80 (m, 4 H); 2.88 (s, 2 H); 1.23 (d, J=6.1 Hz, 6 H).
