실험 절차

To a solution of 6-chloro-N-[(2,4-dimethylthiazol-5-yl)methyl]-5-methyl-2-methylsulfonyl-pyrimidin-4-amine F5 (51 mg, 0.15 mmol) and 3-(quinolin-2-yl)propan-1-ol G6 (25 mg, 0.13 mmol) in 3 mL of THF was added LiHMDS (200 μL of a 1M solution in THF, 0.20 mmol). After stirring for 2 hours, the reaction was quenched by the addition of a saturated ammonium chloride solution. The mixture was partitioned between a saturated solution of NaHCO3 and EtOAc, the layers were separated, and the aqueous layer was extracted twice with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated by rotary evaporation. The residue was purified by silica gel flash column chromatography (EtOAc/hexanes gradient) to provide 17 mg (28%) of G7 as an off-white solid. 1H NMR δ (400 MHz, CDCl3): 8.1-8.0 (2H, m), 7.75 (1H, m), 7.65 (1H, m), 7.5 (1H, m), 7.35 (1H, m), 4.9 (1H, m), 4.7 (2H, d), 4.4 (2H, t), 3.15 (2H, t), 2.6 (3H, s), 2.35 (5H, m), 2.0 (3H, s). HRMS (ES) calculated M+H for C23H24ClN5OS: 454.1463. Found. 454.1455.
