60% | With sodium hydrogencarbonate In isopropyl alcohol for 12 h; Reflux | Compound 18 9 (4.0g, 14.4mmol) was dissolved in IPA (25mL). 20 Ethyl thioxamate (1.60g, 12.0mmol) and 146 NaHCO3 (2.01g, 24.0mmol) were added. The mixture was refluxed for 12h, followed by concentration. The residue was taken in 63 water and extracted with dichloromethane. The organic layer was washed with water, brine and dried over anhydrous Na2SO4 and concentrated to the desired compound (2.2g, 60percent), which is pure enough for the next step. mp: 138–140°C; 1H NMR (300MHz, CDCl3): δ 4.71(s, 2H), 4.48(q, J=12Hz, 2H,), 3.72(m, 2H), 2.96(t, J=5.4Hz, 2H), 2.41(t, J=6.3Hz, 2H), 1,51(s, 9H), 1,44(t, J=1.2Hz, 3H,); MS (ESI) m/z: 335.1 [M+Na]+. |
