2-Iodopropane (174 mg, 1.02 mmol)) was added to a mixture of 4-hydroxy-2-phenoxymethyl-2,3-dihydro-benzofuran-6-carboxylic acid tert-butyl ester (214b) (350 mg, 1.02 mmol) and K2CO3 (141 mg, 1.02 mmol) in DMF (5 mL). The reaction mixture was stirred at 60° C. overnight. The mixture was diluted with H2O (50 mL) and extracted with EtOAc (2×50 mL). The organic layers were washed with H2O (2×70 mL), dried over MgSO4 and concentrated. The residue was purified by flash column chromatograph eluting with 5% EtOAc in hexanes to give a white solid (182 mg, 46% yield). 1H NMR (400 MHz, CDCl3) δ 7.29 (d, J=1.26 Hz, 1 H) 7.22-7.26 (m, 1 H) 7.13 (s, 1 H) 7.07 (s, 1 H) 6.91-7.00 (m, 3 H) 6.85 (d, J=7.58 Hz, 1 H) 5.17-5.25 (m, 1 H) 4.59-4.68 (m, 1 H) 4.07-4.17 (m, 1 H) 3.34 (dd, J=16.55, 9.47 Hz, 1 H) 3.09 (dd, J=16.55, 6.95 Hz, 1 H) 1.58 (s, 9 H) 1.35 (d, J=6.06 Hz, 6 H); LCMS for C23H28O5 m/z 385.20 (M+H)+.
