N-(5-(3-aminophenyl)thiazolo[5,4-b]pyridin-2-yl)acetamide (102.6 mg, 0.361 mmol) was suspended in DCM (2.7 ml) and pyridine (0.050 ml, 0.61 mmol) and 4-methoxybenzene-1-sulfonyl chloride (107.2 mg, 0.519 mmol) were added. The reaction was stirred under nitrogen at room temperature for about 100 minutes. The, reaction was treated with Et2O and filtered. Solid washed with Et2O, MeOH, and Et2O, then collected and purified on HPLC (10% to 95% MeCN/water with 0.1% TFA over 30 minutes) to afford N-(5-(3-(4-methoxyphenylsulfonamido)phenyl)thiazolo[5,4-b]pyridin-2-yl)acetamide (62.7 mg, 38% yield). MS (ESI pos. ion) m/z: 455. Calculated exact mass for C21H18N4O4S2 454.
