The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (659 mg). 1H NMR (300 MHz, DMSO-d6) δ 0.21-0.49 (2H, m), 0.49-0.69 (2H, m), 1.07-1.46 (1H, m), 4.00 (2H, d, J=7.2 Hz), 8.53 (2H, s).
