[0028] 1.7 Thienomorphine (C 1 ) preparation
[0029] 1.2g (2mmol) vii 1 Dissolve in 5ml of anhydrous tetrahydrofuran, add 2ml of 2M LiAlH dropwise under stirring 4 Tetrahydrofuran solution; after adding, stir overnight at room temperature; then add magnesium sulfate heptahydrate in batches until no gas is released. Filtrate, evaporate the filtrate to dryness under reduced pressure, separate by silica gel column chromatography, elute with petroleum ether: dichloromethane: methanol = 4: 1: 0.1, collect the required components, and recrystallize with methanol to obtain C 1 0.75g; Dissolve this solid with ethanol, add hydrogen chloride ether solution, to pH2, stir, precipitate solid, after standing overnight, filter and wash with anhydrous ether to obtain C 1 ·HCl 0.61g, melting point: >200°C. 1 H-NMR (400MHz, DMSO-d6): 9.62 (br, 1H); 9.39 (br, 1H); 7.26 (m, 1H); 7.01 (d, 1H); 6.91 (m, 1H); 1H); 6.55(d, 1H); 4.64(br, 1H); 4.54(s, 1H); 3.90(d, 1H); 3.41(s, 3H); 3.28(m, 2H); 3...
