Reaction Steps

4-tert-butyl-N-(4-chloro-2-(4-iodo-5-methyl 1H-1,2,3-triazol-1-yl)phenyl)benzenesulfonamide (synthesized according to general procedure P, 200 mg, 0.38 mmol) was placed in a 10 mL 2-neck flask and the flask was evacuated and purged with N2 three times. To the solid was added THF (1.9 mL) and the solution was lowered to −78° C. PhMgBr (0.21 mL, 1.8 M) was added to the solution and it was stirred for 15 minutes. n-BuLi (0.19 mL, 2.0 M) was subsequently added and the reaction was stirred an additional 30 minutes. Acetaldehyde (0.085 mL, 1.5 mmol) was added to the reaction and it was warmed to 0° C. The solution was subsequently quenched with 10% HCl and the aqueous layer was extracted three times with EtOac. The combined organics were dried over sodium sulfate, concentrated in vacuo, and purified by HPLC to afford 4-tert-butyl-N-(4-chloro-2-(4-(1-hydroxyethyl)-5-methyl-1H-1,2,3-triazol-1-yl)phenyl)benzenesulfonamide as a white solid: MS (ES) M+H expected 449.1, found 449.1.
