The reaction mixture was stirred for 4 h and TLC indicated completion of the reaction. The reaction mixture was washed with 10% aqueous citric acid and brine, dried over Na2SO4, and concentrated to provide the title compound (1.7 g, 100%) as red oil. 1H NMR (300 MHz, DMSO) δ ppm 0.86 (t, J=6.7 Hz, 3H), 1.16-1.38 (m, 4H), 1.57 (m, 2H), 3.03 (m, 1H), 3.87 (m, 2H), 4.91 (s, 2H), 7.41 (m, 5H).
