Conditions

Temperature: 200 °C

Procedure

117 mg (0.50 mmol, 1 eq) 2-chloro-5-[(2-methyl-1,3-thiazol-4-yl)ethynyl]pyrimidine, 0.50 mL (5 mmol, 10 eq) 2-methylpyrrolidine and 1 mL NMP were combined. The reaction mixture was heated at 200° C. for 15 min, quenched with pH 10 PBS, extracted with DCM. Silica gel chromatography (gradient 10% to 40% EtOAc/Hexanes) gave 2-(2-methylpyrrolidin-1-yl)-5-[(2-methyl-1,3-thiazol-4-yl)ethynyl]pyrimidine (L-001152863). LC-MS calculated for C15H16N4S 284, observed m/e 285.3 (M+H)+.
