실험 절차

To a solution of 4-amino-2-chloropyridine (53.3 mg, 0.415 mmol) in THF (277 μl) cooled to −78° C. under nitrogen, LiHMDS (415 μl, 0.415 mmol) was added dropwise. The reaction mixture was warmed up to rt, then was stirred for 30 minutes. To the reaction mixture cooled back to −78° C., 1-(4′-(cyclopropylmethyl)-2-(methylsulfinyl)-4,5′-bipyrimidin-2′-ylamino)-2-methylpropan-2-ol (5-3) (50 mg, 0.138 mmol) was added, and the reaction mixture was warmed up to rt, then was stirred for additional 1 hour. According to LC/MS, the reaction was complete. The crude product was purified by reverse-phase HPLC [30-100% organic phase over 15 minutes] followed by Biotage™ silica gel chromatography [10 g SNAP column, 100% DCM to 12% MeOH/DCM] to obtain the desired product (29 mg, 49%).
