実験手順

To a solution of 2-(3-Cyano-phenoxy)-nicotinic acid (0.140 g 0.600 mmole), BOP (0.260 grams, 0.600 mmole) and DIEA (0.310 μl, 1.8 mmole) in dimethylformamide (5 ml) was added 4-Aminomethyl-benzenesulfonamide (0.135 grams, 0.600 mmole) and stirred at room temperature over night. The reaction was quenched with water and extracted with ethyl acetate. The combined organics were washed with alternating portions of 5% citric acid and sat'd bicarb, dried over Na2SO4, filtered and concentrated to a product which was recrystalized from ethyl acetate to give a white solid (0.100 g). M.P. 179-180° C.; Anal. calcd. for C20H16N4O4S; C, 58.81; H, 3.95; N, 13.72. Found: C, 57.47; H, 4.15; N. 13.45.
