Reaction Steps

The title compound was prepared by combining methanesulfonic acid 2-{4-[5-(2-tert-butyl-5-methyl-phenylsulfanyl)-4-hydroxy-6-oxo-2-phenethyl-3,6-dihydro-2H-pyran-2-yl]-phenoxy} -ethyl ester (0.07 g, 0.1 15 mmol) from the previous paragraph, K2CO3 (0.08 g, 0.57 mmol), and morpholine (0.15 mL, 1.72 mmol) in DMF (2 mL). The reaction was stirred overnight at room temperature then combined with H2O and acidified to pH 6.0 with 1N HCl. The product was extracted with EtOAc, dried (MgSO4) and concentrated. Purification by silica gel chromatography, eluting with MeOH:CH2Cl2 :hexane (1:50:50) gave the title compound, m.p. 140-150° C. 1H NMR (CDCl3) δ 1.48 (s, 9 H), 1.80 (s, 3 H), 2.17-2.29 (m, 3 H), 2.38 (m, 1 H), 2.63 (m, 4 H), 2.84 (m, 2 H), 3.21 (dd, 2 H), 3.74 (m, 4 H), 4.00 (m, 2 H), 6.15 (s, 1 H), 6.78 (m, 2 H), 7.05 (d, 2 H), 7.10-7.22 (m, 5 H), 7.32 (d, 2 H).
