실험 절차

To a 0° C. solution of 4-methyl-2-[3-(1-methyl-piperidin-4-yl)-propylamino]-pyrimidine-5-carboxylic acid ethyl ester (0.20 g, 0.63 mmol) in THF (6 mL) was added diisobutylaluminum hydride (1 M in hexanes; 1.25 mL, 1.25 mmol) dropwise. The mixture was warmed to rt over 1 h. The reaction was quenched with 1 M H2SO4 (2 mL). The mixture was neutralized with satd. aq. NaHCO3, and diluted with MeOH (2 mL), CHCl3 (10 mL), and satd. aq. sodium potassium tartrate (10 mL). The mixture was stirred vigourously until the layers separated. The organic layer was dried (Na2SO4) and concentrated to give the crude product (138 mg), which was used in the next step without further purification. 1H NMR (CDCl3): 8.07 (s, 1H), 4.52 (s, 2H), 3.42-3.33 (m, 2H), 2.88-2.74 (m, 2H), 2.41 (s, 3H), 2.23 (s, 3H), 1.93-1.83 (m, 2H), 1.72-1.53 (m, 4H), 1.35-1.16 (m, 5H).
