93% | With sodium carbonate; In 1,4-dioxane; water; at 0 - 20℃; for 24h;pH 8 - 9; | a) 2-[2-(tert-Butoxycarbonyl)hydrazino]benzoic acid (IV'A.1); To a solution of 3 g of <strong>[33906-30-8]2-hydrazinobenzoic acid hydrochloride</strong> (16 mmol, 1 eq.) in dioxane (1 mL/mmol) is added a solution of 3.81 g of Boc2O (17.5 mmol, 1.1 eq.) in dioxane (0.4 mL/mmol). The solution is cooled to 0 C. and aqueous 5% Na2CO3 solution is added dropwise to pH 8-9. The solution is then warmed to room temperature and stirring is continued for 24 hours. The dioxane is evaporated off. The medium is taken up in water and then acidified with 1N HCl solution to pH 1. The mixture is extracted three times with ethyl acetate. The combined organic phases are dried over sodium sulfate, filtered and evaporated to dryness. The powder obtained is triturated with petroleum ether and then dried under vacuum to give 3.75 g of compound (IV'A.1) (yield 93%).1H NMR 300 MHz (DMSO): delta (ppm)=1.41 (s, 9H, C(CH3)3); 6.75 (t, J=7.5 Hz, 1H, H3); 6.86 (d, J=8.1 Hz, 1H, H5); 7.43 (t, J=7.8 Hz, 1H, H4); 7.81 (d, J=8.1 Hz, 1H, H6); 8.88 (s, 1H, NH); 9.05 (s, 1H, NH); 13 (s, 1H, COOH).IR (KBr): nuNH=3381.6 cm-1; nuCsp3-H=2971.7 cm-1; nuCO=1697.6 cm-1 and 1676.7 cm-1; nuCC=1609.1 cm-1 and 1587.2 cm-1.Melting point=146 C. |
93% | With sodium carbonate; In 1,4-dioxane; water; at 20℃; for 24h;pH 8 - 9; | A solution of <strong>[33906-30-8]2-hydrazinobenzoic acid hydrochloride</strong>(l: l) (3.00 g, 15.9 mmol) in dioxane (55 ml) was treated with a solution of di-tert-butyl dicarbonate (3.8 g, 17 mmol) in dioxane (7 ml). The resulting solution was cooled to 0 C and the solution was adjust to pH 8-9 with an aqueous solution of sodium carbonate (5% w/w). The reaction mixture was stirred 24 h at room temperature. The dioxane was evaporated, the residue was retaken in water. The solution was brought to pH =1 with an aqueous solution of hydrogenchloride (IN). The mixture was extracted three times with ethyl acetate. The combined organic phases were dried over sodium sulfate and evaporated. The resulting solid was triturated with petroleum ether, filtered off and dried under high vacuum affording 3.75 g (93 % of th.) of the title compound.
