The title compound of Example 365, step 3 in anhydrous THF was treated with excess 1M LAH in THF at room temperature. After about 30 min, ice, water, methanol and 1M HCl were added followed by saturated aqueous NaHCO3 and EA extractive work up. Silica gel chromatography (EA, followed by 5% methanol in EA) gave the title compound as a clear glass. 1H NMR: (DMSO-d6, 400 MHz) δ ppm 0.32 (br. s., 2H) 0.54 (br. s., 2H) 1.03-1.30 (m, 4H) 3.45 (br. s., 3H) 3.94 (br. s., 2H) 4.09 (br. s., 2H) 5.03 (br. s., 1H) 7.05 (br. s., 1H) 7.22 (br. s., 1H) 7.62 (br. s., 1H) 7.78 (br. s., 1H). 1H NMR: (DMSO-d6/DCl, 400 MHz) δ ppm 0.29 (br. s., 2H) 0.55 (br. s., 2H) 1.10 (br. s., 4H) 3.25 (br. s., 2H) 3.45 (br. s., 2H) 3.51 (br. s., 3H) 3.93 (br. s., 2H) 4.43 (br. s., 2H) 7.27 (br. s., 1H) 7.69 (br. s., 1H) 7.84 (br. s., 2H).
