Procedure

A 30 mL scintillation vial was charged with 4-tert-butyl-N-[4-chloro-2-(5-diethoxymethyl-[1,2,3]triazol-1-yl)-phenyl]-benzenesulfonamide (synthesized according to general procedure Q, 1.0 g, 2.0 mmol) and Ac2O/pyridine (1:2 v/v, 6 mL), and stirred at room temperature for 4 hours. The reaction mixture was subsequently diluted with Et2O and washed with 1 M HCl, saturated NaHCO3, and brine. The combined organics were then dried over Na2SO4 and concentrated in vacuo. The resultant product (35 mg, 0.075 mmol) and dimethyl amine (80 μL, 2.0 M in THF) were combined in a 4 mL scintillation vial and stirred for 30 minutes. NaBH(OAc)3 (32 mg, 0.17 mmol) was then added and the reaction was stirred for 12 hours at room temperature. The reaction mixture was subsequently diluted with Et2O, washed with 1 M HCl, and the combined organics were purified by preparative TLC to generate 4-tert-butyl-N-[4-chloro-2-(5-dimethylaminomethyl-[1,2,3]triazol-1-yl)phenyl]-benzenesulfonamide: MS (ES) M+H expected 448.2, found 448.4.
