Sodium bis(trimethylsilyl)amide (164 μL, 1.0 M, 0.164 mmol) was added to a solution of 1-butanethiol (28.1 μL, 0.262 mmol) stirring in DMF (327 μL) at room temperature in an oven-dried vial. Stirred for 15 minutes, then added 4-[5-(3-methyl-5-{[4-(methylsulfonyl)-2-pyrimidinyl]amino}phenyl)-1,3-thiazol-2-yl]-1,4-diazepan-2-one (30 mg, 0.065 mmol). Stirred at room temperature for 30 minutes, diluted with ethyl acetate (10 mL), and washed with 1:1 water:brine (10 mL). The organic extracts were dried (Na2SO4), filtered, and concentrated in vacuo. Purified by CombiFlash (100:0 to 0:20 dichloromethane:methanol) to afford 4-[5-(3-{[4-(butylsulfanyl)pyrimidin-2-yl]amino}-5-methylphenyl)-1,3-thiazol-2-yl]-1,4-diazepan-2-one (14.6 mg, 0.031 mmol, 48% yield) as a white solid.
