YieldReaction ConditionsOperation in experiment
acetic acid; In toluene; at 70℃; for 9h; To a stirred solution of tert-butyl 4-(3-aminopyridin-2-yl)piperazine-l -carboxylate (78.4 mg, 0.282 mmol), 2-aminopyrimidine-4-carbaldehyde (45.0 mg, 0.366 mmol) and toluene (3 ml) at room temperature was added acetic acid (0.07 ml, 0.2M in PhMe, 0.0141 mmol). After stirring for 9 h at 70 C, the reaction mixture was concentrated under reduced pressure. To a stirred solution of the resulting crude material, dichloromethane (0.5 ml) and methanol (3 ml) at room temperature was added sodium cyanoborohydride (35.4 mg, 0.564 mmol). After stirring for 5 h at 70 C, water (2 ml) was added and the resulting solution was extracted with EtOAc (5x2 ml). The combined organic layers were concentrated and purified by silica gel column chromatography (Hexane/EtOAc = 1 :2, then CH2Cl2/MeOH = 30: 1? 20: 1) to give tert-butyl 4-(3 -((2-aminopyrimidin-4-yl)methylamino)pyridin-2-yl)piperazine- 1 -carboxylate (60.0 mg, 55%) as a pale brown oil. MS (EI) for Ci9H27 702: 386.2 (MH+).

YieldReaction ConditionsOperation in experiment
With sodium tetrahydroborate; potassium carbonate; at 0 - 5℃; for 0.5h;pH 8.0; The solution of 5.01 g 4-(dimethoxymethyl)pyrimidin-2-amine (29.5 mmol) in 100 mL 2Naq. HCI was stirred at 60°C for 5h. Reaction mixture was cooled to 0°C, then 7.60 g NaOH(190 mmol) was added portionwise. The pH was adjusted to 8 using 10percent K2C03 solution, then 2.24 g sodium borohydride (59.0 mmol) was added portionwise keeping the temperature under 5°C and stirred for 30 mm at 0°C. The reaction mixture was extracted with EtOAc, the combined organic phases were dried over Na2SO4 and concentrated underreduced pressure. The crude product was purified via flash chromatography (MeOH - containing I percentN113- and DCM).?FT NMR (400 MHz, DMSO-d5): 8,20 (d, 111), 6.66 (d, 111), 6.49 (br s, 211), 5.35 (t, IH), 4.30 (d, 211).
