Reaction Steps

Combine 6-(4-{[tert-Butoxycarbonyl-(3-methyl-butyl)-amino]-methyl}-phenoxy)-nicotinic acid (0.090 g, 0.21 mmol), CH2Cl2 (5 mL), EDC (0.048 g, 0.25 mmol), HOBt (0.034 g, 0.25 mmol), Hunig's Base (92 uL, 0.53 mmol), and Methylamine Hydrochloride (0.014 g, 0.21 mmol) in a 7 mL reaction vial. After reactions shake for 72 hours, add 10% Citric acid, followed by 10% NaHCO3, and then add the organic mixture to a Celite column. Elute with CH2Cl2, concentrate, and flash chromatograph using 2:1 Ethyl acetate:Hexanes eluent to afford 56.2 mg (63% yield) of the title compound: 1H NMR (500 MHz, CDCl3); 0.9 (6H, d), 1.3-1.6 (12H, m), 3.0 (3H, s), 3.1-3.3 (2H, m), 4.3-4.5 (2H, m), 6.3 (1H, br s), 6.9 (1H, d), 7.1 (2H, d), 7.2-7.4 (2H, m), 8.1 (1H, d), 8.5 (1H, s); MS m/z 328 (M−100, Boc).
