実験手順

Pyrrolidine (88 μL, 1.06 mmol) was added to a solution of 5-(3-oxopropyl)-2-phenyl-N-(2-(thiazolo[5,4-b]pyridin-2-yl)phenyl)thiazole-4-carboxamide (250 mg, 0.53 mmol) and AcOH (127 mg, 2.1 mmol) in dichloroethane (DCE) (10 mL). The reaction mixture was stirred for 1 h. Sodium triacetoxyborohydride (449 mg, 2.1 mmol) was added and stirring continued for 16 h. The reaction mixture was poured into sat aq NaHCO3 and extracted with DCM. The combined organics were washed with brine, dried (MgSO4), and concentrated. The crude product was purified by MPLC eluting with CH2Cl2/MeOH+1% TEA (0-10% gradient) to give the title compound (87 mg, 31% yield). MS Calcd for C29H27N5OS2: 525.17. Found (M+H)+ m/z=526.
