Downstream synthetic route of 149353-75-3

149353-75-3, The synthetic route of 149353-75-3 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.149353-75-3,4-(1-(tert-Butoxycarbonyl)piperidin-4-yl)benzoic acid,as a common compound, the synthetic route is as follows.

1- (N-t-Butoxycarbonylamino)-2-aminobenzene (Method 17,3. 1 g, 14.7 mmol) was added to a stirred solution of 4- (l-t-butoxycarbonylpiperidin-4-yl) benzoic acid (4.1 g, 13.4 mmol) in DMF (50 ml) and the mixture stirred at ambient temperature for 10 minutes. 4- (4, 6- dimethoxy-1, 3,5-triazinyl-2-yl)-4-methylmorpholinium chloride (Method 18,4. 45 g, 16.1 mmol) was added and the mixture stirred at ambient temperature for 24 hours. The solvent was evaporated and the residue was dissolved in ethyl acetate (100 ml) and washed with water. The organics were dried over magnesium sulfate, filtered and evaporated. The resultant gum was purified by flash chromatography using 1% methanol/dichloromethane to give the title compound as a foam (5.44 g, 82%) ; NMR Spectrum : (DMSO-ds) 1.41 (s, 9H), 1.43 (s, 9H), 1.54 (m, 2H), 1.77 (m, 2H), 2.79 (m, 3H), 4. 08 (m, 2H), 7.15 (m, 2H), 7.40 (d, 2H), 7.52 (m, 2H), 7. 87 (d, 2H), 8.60 (br, 1H), 9.74 (br, 1H), Mass Spectrum: (M+E-Boc) 396.
