Reaction Steps

To a solution of 2,4-dichloro-6-methylpyrimidine (998 mg, 6.0 mmol) in tetrahydrofurane (30 mL) was added under stirring N,N-diisopropyl ethyl amine (853 mg, 6.6 mmol) and pyrrolidine (469 mg, 6.6 mmol) and the reaction was stirred over night at 20° C. The solvent was evaporated under reduced pressure and the residue was taken up in water and extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate, filtered and evaporated under reduced pressure to dryness. The residue was purified by column chromatography on silica gel using heptane/ethyl acetate (9:1 to 7:3 v/v) as eluent to yield the title compound (694 mg, 58%) as white crystals. MS ISP (m/e): 198.1/200.1 (100/40) [(M+H)+]. 1H NMR (DMSO-D6, 300 MHz): δ (ppm)=6.35 (s, 1H), 3.44 (m, 2H), 3.30 (m, 2H), 2.29 (s, 3H), 1.94 (m, 4H).
