Ex-53A: A solution of 4-acetyl-benzenesulfonyl chloride (1.94 g, 8.89 mmol) and triethylamine (1.85 mL, 13.3 mmol) in anhydrous THF (15 mL) was treated with 2-(aminomethyl)pyridine (1.01 g, 9.34 mmol) at room temperature under nitrogen. The reaction mixture was stirred for 5 minutes and a precipitate formed. The reaction mixture was diluted with water (10 mL) and suction filtration gave 4-acetyl-N-pyridin-2-ylmethylbenzenesulfonamide as a yellow solid (1.36 g, 65%). 1H-NMR (300 MHz, DMSO-d6) 8.38 (m, 3H), 8.06 (d, 2H, J=9.0 Hz), 7.87 (d, 2H, J=7.8 Hz), 7.58 (d, 1H, J=8.7 Hz), 7.25 (dd, 1H, J=5.4, 4.5 Hz), 4.04 (d, 2H, J=3.9 Hz), 2.60 (s, 3H).
