YieldReaction ConditionsOperation in experiment
With diisopropyl-carbodiimide; at 0 - 20℃; [0078] N-BABA, compound 2, is reacted with N -hydroxysuccinimide (NHS) under conventional conditions well known in the art to generate SBAP, compound 3. Specially, N- BABA is combined with at least a stoichiometric amount of NHS in a suitable inert solvent such as methanol, ethanol, isopropanol and the like. The resulting solution is stirred at about 20 ± 5C until a clear solution is obtained. N-Diisopropylcarbodiimide is then added to the reaction mixture and mix with the generation of solids. The system is then cooled to 0 ± 5C and resulting SBAP is provided by filtration. Further purification entails prechilling a mixture of isopropanol and heptanes and washing the filter cakes followed by drying wet cake in a vacuum oven at about 30C. The resulting SBAP is used as is in the coupling reaction with the TT monomer.
YieldReaction ConditionsOperation in experiment
Succinimidyl 3-(bromoacetamido)propionate (SBAP). To a solution of β-bromoacetylβ-alanine (21.00 g, 100 mmol) and N-hydroxysuccinimide (13.01 g, 113 mmol) in 2-propanol (280 mL) at room temperature was added 1,3-diisopropyl-carbodiimide (16.0 mL, 101 mmol). After 8-10 min, oily precipitation of the product began, and the walls of the container were scratched to induce crystallization. The mixture was allowed to stand 1 h at room temperature and overnight at 4 C. The crystals were collected, washed with 2-propanol (30 mL), and redissolved in 2-propanol (200 mL brought to reflux). After an overnight stand at 4 C., the crystals were collected, washed with 2-propanol then hexane, and dried under vacuum/CaCl2. Yield, 22.9 g (74.6% of theory) mp 107-110.5 C. [lit.

After 1 hour, (R)-2-amino-3-mercaptopropanoic acid (0.060 g, 0.493 mmol) as a solution in water (1 ml) was added. After 1 hour, a few drops of TFA were added to form a homogeneous solution and the mixture was purified by chromatography to give the title compound. 1H NMR (400 MHz, DMSO-d6) δ 9.28 (t, J=5.9 Hz, 1H), 8.85 (d, J=7.0 Hz, 1H), 8.47 (s, 2H), 8.30 (d, J=1.9 Hz, 1H), 8.21 (t, J=5.6 Hz, 1H), 8.17-8.09 (m, 2H), 7.84 (s, 1H), 7.81-7.74 (m, 2H), 7.44 (dd, J=7.0, 1.1 Hz, 1H), 7.27 (d, J=3.8 Hz, 1H), 4.65 (d, J=5.8 Hz, 2H), 4.20 (dd, J=7.5, 4.3 Hz, 1H), 4.06 (s, 2H), 3.90-3.78 (m, 2H), 3.35-2.94 (m, 8H), 2.59-2.41 (m, 2H), 1.57-1.19 (m, 4H), 0.95 (s, 3H); MS (ESI(+)) m/e 667 (M+H)+.
