86.02% | With tin(II) chloride dihdyrate; In ethanol; for 5h;Reflux; | In the second step, 7.80 g (17.7 mmol) of Compound 1, 12.00 g (53.1 mmol) of stannous chloride dihydrate and 80 ml of absolute ethanol were added to a 250 ml two-necked flask.The reaction was refluxed for 5 h, and after completion of the reaction, the reaction mixture was evaporated to dryness using a rotary evaporator. Adjust the reaction solution to alkaline. The resulting mixture was extracted with dichloromethane. The obtained dichloromethane solution was dried over anhydrous magnesium sulfate, then suction filtered and dried. A white solid was obtained, which was purified and concentrated to give a white solid (yield: 86.02%). |
81% | With palladium 10% on activated carbon; hydrazine hydrate; In ethanol; for 12h;Reflux; | Compound 8 (100 mg, 0.25 mmol), a mass fraction of 10% palladium on carbon (2 mg), hydrazine hydrate (50 μL) and stirred under reflux in ethanol for 12 h;After cooling to room temperature, the palladium on carbon was removed by filtration, and the solvent was removed by rotary evaporation to obtain compound 9. Yield: 81%. |

90% | With trifluoroacetic acid; In ethanol; for 3h;Reflux; | Compounds 5 (0.37g, 1.0mmol) and 6 (0.38g, 1.0mmol) were first dispersed in ethanol (20mL). Two drops of trifluoroacetic acid were added and the mixture was refluxed for 3h. Then, the mixture was cooled to room temperature and filtered to afford TPMA (0.65g) as a yellowish powder: Yield: 90%. m.p. >300C. 1H NMR (400MHz, C6D4Cl2) δ (ppm) 8.80 (s, 1H), 8.48 (d, J=9.7Hz, 4H), 8.40 (d, J=8.0Hz, 2H), 7.89 (d, J=7.8Hz, 2H), 7.82 (d, J=8.1Hz, 2H), 7.76 (d, J=8.0Hz, 2H), 7.74-7.67 (m, 8H), 1.68 (s, 36H) (See Fig.S20). 13C NMR (100MHz, C6D4Cl2) δ (ppm) 134.21, 133.27, 132.93, 132.18, 131.57, 131.47, 131.03, 130.84, 130.58, 129.60, 129.38, 129.13, 128.56, 128.30, 128.05, 127.82, 34.76, 32.14, 32.10, 32.04, 25.91 (See Fig.S21).
