Procedure
Combine 6-(4-Formyl-phenoxy)-nicotinic acid (250.0 mg, 1.03 mmol), EDC (237.0 mg, 1.23 mmol), HOBt (166.2 mg, 1.23 mmol), and Piperidine (0.10 mL, 1.03 mmol) in CH2Cl2 (6 mL). After reaction stirs at room temperature under a Nitrogen atmosphere for 24 hours, concentrate the reaction mixture using a rotovap, add Ethyl acetate and wash with 0.1N HCl, 10% NaHCO3 Brine, and dry over Na2SO4. After concentrating the reaction mixture, flash chromatograph using 2:1 Ethyl acetate:Hexanes to afford 144.1 mg (45% yield) of the title compound as a white foam: 1H NMR (500 MHz, CDCl3); 1.5-1.8 (6H, m), 3.3-3.8 (4H, m), 7.0-7.1 (1H, m), 7.3-7.4 (2H, m), 7.8-8.0 (3H, m), 8.3 (1H, m), 9.9 (1H, s); MS m/z 311 (M+1).
