To a stirred solution of suberoyl chloride (1.00 mL, 5.55 mmol) in THF (40 mL) at 0° C. was added a solution of benzylamine (0.61 mL, 5.55 mmol) and DIEA (1.45 mL, 8.33 mmol) in THF (10 mL) dropwise. The mixture was allowed to warm to ambient temperature and stirred for 1 h. Then, HCl (10 mL, 1 N) was added and the mixture stirred for 0.5 h. The contents were diluted with EtOAc (30 mL) and the layers separated. The aqueous portion was extracted with EtOAc (3×10 mL), the organics combined, washed with brine (5 mL), and dried over MgSO4. Filtration and concentration under reduced pressure left 49 as an off-white solid. 1H-NMR (300 MHz, DMSO-d6) δ 11.98 (br s, 1H), 9.80 (t, 1H), 7.32 (m, 2H), 7.23 (m, 3H), 4.25 (d, 2H), 2.19 (t, 2H), 2.12 (t, 2H), 1.50 (m, 4H), 1.25 (m, 4H).
