Reaction Steps
A stirred solution of compound 5c (14 g, 51 mmol) in THF (400 mL) was cooled in an ice-water bath under an argon atmosphere and treated with lithium aluminium hydride (1M in THF, 51 mL, 51 mmol) dropwise. After 1 h, saturated NH4Cl solution (20 mL) was added slowly to quench the reaction, followed by 200 mL of water. The reaction mixture was extracted with EtOAc (2×100 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated to give compound 5d as a white solid. 1H-NMR (400 MHz, CDCl3) δ (ppm): 7.98 (d, J=5.6 Hz, 1H), 7.77 (s, 1H), 6.05 (d, J=5.9 Hz, 1H), 4.81 (s, 2H), 3.91 (s, 8H), 2.71 (br. s., 1H).
