Reaction Steps

To a 10-mL microwave-rated vial with magnetic stir bar at r.t. was added 4-{3-[(2-Chloro-pyridine-4-carbonyl)-amino]-benzylamino}-quinazoline-8-carboxylic acid amide (0.05 g, 0.115 mmol, 1 eq.), t-BuOH (2 mL), DMSO (1 mL), and pyrrolidine (0.1 mL, 1.15 mmol, 10 eq.). The vial was capped and heated under microwave conditions (50 W, 3 min. ramp, 110° C., STND, 1 hr. hold time) followed by addition of another aliquot of pyrrolidine (0.1 mL) then microwaved (70 W, 3 min. ramp, 140° C., STND, 1 hr. hold time). Reaction was diluted with water (20 mL) and extracted with DCM (3×30 mL). The combined organics were washed with brine, dried (e.g., Na2SO4), filtered and concentrated. The resulting residue was purified by column chromatography (ISCO CombiFlash) using a 0-30% gradient (10% MeOH in EtOAc/EtOAc) afforded 25 mg (49% yield). LCMS (ESI) 468 (M+H).
