实验过程
Following the general procedure for the formation of the corresponding sodium carboxylates of acyloxyalkyl carbamates of tranexamic acid, 946 mg (3.0 mmol) of trans-4-{[1-(butanoyloxy)ethoxycarbonyl]aminomethyl}-cyclohexanecarboxylic acid 10 was reacted with 252 mg (3.0 mmol) of sodium bicarbonate (NaHCO3) in 20 mL of a mixture of acetonitrile and water (1:1) to yield 1.02 g (quant.) of the title compound 11 as a colorless powder. 1H NMR (400 MHz, DMSO-d6): δ=0.73-0.84 (m, 2H), 0.87 (t, J=6.8 hz, 3H) 1.08-1.20 (m, 2H), 1.20-1.32 (m, 1H), 1.38 (d, J=5.2 Hz, 3H), 1.46-1.56 (m, 2H), 1.60-1.74 (br. m, 3H), 1.76-1.83 (br. m, 2H), 2.25 (t, J=7.2 Hz, 2H), 2.78 (t, J=6.0 Hz, 2H), 6.65 (q, J=5.2 Hz, 1H), 7.41 (t, J=5.6 Hz, 1H). MS (ESI) m/z 338.16 (M+Na)+; 314.18 (M−H)−.
