170097-67-3, 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-6-carboxylic acid is a tetrahydroisoquinoline compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
3,4-Dihydro-lH-isoquinoline-2,6-dicarboxylic acid 2-tert-buty ester (50 mg, 0.18 mmol), EDC (38.3 mg, 0.2 mmol) and EtaOBt (24.3 mg, 0.18 mmol) were combined in a reaction vial, and DMF (1 mL) was added. To the solution thus formed, N-methylmorpholine (0.22 mL, 0.2 mmol) was added and the reaction mixture was agitated for 1 hour. The urea, 1- (3-amino-benzyl)-3-(4-cyano-phenyl)-urea (40 mg, 0.15 mmol), prepared as described above, was then added as a solution in DMF (0.3 mL), and the reaction mixture was agitated for 48 h. The reaction mixture was diluted to 6 mL with dichloromethane, washed with IN HCl (3×2 mL), NaHCO3 (satd. aq., 3×2 mL, and brine (1 x 2 mL), dried and evaporated to 59 mg of an oil (95% yield). This intermediate (6-{3-[3-(4-cyano- phenyl)-ureidomethyl]-phenylcarbamoyl}-3,4-dihydro-lH-isoquinoline-2-carboxylic acid tert-butyl ester) was dissolved in dichloromethane (1 mL) and TFA (0.4 mL) was added. The reaction mixture was stirred for 2 h, then the solvents were evaporated and the resulting residue was purified directly by preparative EtaPLC using an acetonitrile/water/formic acid gradient providing the title compound (20 mg, 48% yield), MS analysis electrospray, 426 (M+Eta).
170097-67-3, The synthetic route of 170097-67-3 has been constantly updated, and we look forward to future research findings.
