実験手順

To a stirred solution at −78° C. containing 486 mg (1.58 mmol) of 5-(benzyloxy)-2-(2,5-dimethyl-1H-pyrrol-1-yl)-4,6-dimethylpyrimidine and 281 mg (1.05 mmol) of 1-bromo-9-(methoxymethoxy)nonane in 10 mL of anhydrous THF was added 987 μL (1.58 mmol) of a 1.6 M solution of n-BuLi in pentane. The reaction mixture was stirred under argon atmosphere at 23° C. for 30 min. The reaction was quenched with saturated aqueous ammonium chloride and then poured into 50 mL of water. The mixture was then extracted with two 50-mL portions of ethyl acetate. The combined organic layer was washed with 80 mL of brine, dried (MgSO4) and concentrated under diminished pressure. The residue was purified by chromatography on a silica gel column (15×3 cm). Elution with 5:1 hexanes-ethyl acetate afforded the expected product as a light yellow oil: yield 289 mg (56%); silica gel TLC Rf 0.55 (5:1 hexanes-ethyl acetate); 1H NMR (CDCl381.33 (m, 12H), 1.60 (m, 2H), 1.82 (m, 2H), 2.33 (s, 6H), 2.49 (s, 3H), 2.79 (dd, 2H, J=7.6, 7.6 Hz), 3.36 (s, 3H), 3.52 (t, 2H, J=6.4 Hz), 4.62 (s, 2H), 4.90 (s, 2H), 5.87 (s, 2H) and 7.37-7.48 (m, 5H); 13C NMR (CDCl3) δ14.4, 14.4, 19.3, 26.2, 27.7, 29.4, 29.4, 29.5, 29.5, 29.6, 29.8, 31.6, 55.1, 67.9, 75.7, 96.4, 108.0, 108.0, 128.0, 128.58, 128.62, 128.7, 129.3, 136.2, 147.4, 147.4, 152.6, 161.6, 161.6 and 165.1; mass spectrum (APCI), m/z 494.3395 (M+H)1 (C30H44N3O3 requires 494.3383).
