Procedure:
To a solution of 4-aminopyridine (423 mg, 4.49 mmol) in THF (0.562 mL) cooled to −10° C. was added LHMDS (1M in THF) (1.123 mL, 1.123 mmol). The resulting suspension was warmed to rt and stirred for 15 minutes, after which time it was cooled back to −10° C. and 2-Methanesulfinyl-4′-methyl-[4,5′]bipyrimidinyl-2′-ylamine (20) (70 mg, 0.281 mmol) was then added. The reaction mixture was again warmed to rt and stirred for 1.5 hours. The reaction was quenched by slow addition of saturated ammonium chloride and the volatiles evaporated. The mixture was then diluted with DCM, the layers separated, and the organic layer washed with brine, dried with sodium sulfate, and concentrated. The crude residue was purified by flash column chromatography with a gradient of 2-20% MeOH in DCM. The product was further purified by reverse phase HPLC with a gradient of 10-90% MeCN in water over 15 minutes, to give the desired product as a white solid (1.39 mg, 0.44%). 1H NMR (400 MHz, MeOD) δ ppm 2.57 (s, 3H) 7.13 (d, J=5.56 Hz, 1H) 7.84 (d, J=6.57 Hz, 2H) 8.30 (d, J=6.57 Hz, 2H) 8.50 (s, 1H) 8.57 (d, J=5.05 Hz, 1H).

Procedure:
To a suspension of sodium hydride (2.3 g, 48.5 mmol of 50% oil dispersion) with dimethylformamide (75 ml), and cooled to 3° C. in an ice-salt bath and under a stream of nitrogen was added, dropwise, 1-(4-hydroxy-3-dimethylaminophenyl)ethanone (8.7 g, 48.5 mmol) dissolved in dimethylformamide (150 ml) so that the temperature did not go over 7° C. After the addition was over, the bath was removed and the reaction was stirred at ambient temperature for 45 minutes. The ice bath was reapplied and a solution of 1-bromo-3-chloropropane (8.4 g, 53.4 mmol) in dimethylformamide (25 ml) was added dropwise. After the addition was complete, the reaction was stirred for 18 hours at ambient temperature under nitrogen. The reaction was chilled to 7° C. in an ice bath and water (200 ml) was carefully added. After stirring for 5 minutes, the aqueous mixture was extracted with ethyl acetate (5×200 ml). The ethyl acetate extract was washed with water (2×50 ml), dried with MgSO4, and concentrated to yield 22.2 g of a black oily liquid. The compound was purified by prep HPLC, and combination of appropriate fractions gave 5.0 g of brown oil.
