Reaction Steps

To a 25 mL round bottomed flask cooled to 0° C. was added 2-amino-4,6-di-chloro-5-formyl-pyrimidine (192 mg, 1.0 mmol, 1.0 eq.), THF (10 mL), DIEA (0.34 mL, 2.0 mmol, 2.0 eq.), and 2-amino-N-(3-trifluoromethyl-phenyl)-acetamide (245 mg, 1.0 mmol, 1.0 eq.). The reaction mixture was warmed to RT and allowed to stir overnight before quenching with H2O (10 mL) and EtOAc (50 mL). The EtOAc layer washed with brine, dried with Na2SO4, and concentrated to give crude product as a solid. The solid was then rinsed with 5:95 EtOAc:Hexanes to give pure 2-(2-Amino-6-chloro-5-formyl-pyrimidin-4-ylamino)-N-(3-trifluoromethyl-phenyl)-acetamide as a yellow solid (159 mg, 43%). LC/MSD (HP Series 1100 MSD): Expected MW: 373, Observed M+H, 374.0, Retention time: 1.45 min. ANALYTICAL HPLC: >95%, Retention time: 4.15 min (8 minute run). 1H-NMR (d6-DMSO): 10.5 (s, 1H), 9.9 (s, 1H), 9.42 (t, 1H), 8.08 (s, 1H), 7.80 (d, 1H), 7.59 (t, 1H), 7.42 (d, 1H), 4.40 (d, 2H) ppm.
