실험 절차

To a 20-mL scintillation vial were added the product from Example 96 (118 mg, 0.300 mmol), dimethylamine hydrochloride (Aldrich, 36.7 mg, 0.450 mmol), and 2-(1H-benzo[d][1,2,3]tria-zol-1-yl)-1,1,3,3-tetramethylisouronium tetrafluoroborate (TBTU, Bachem, 144 mg, 0.450 mmol). Anhydrous acetonitrile (3 mL) was added to form a yellow slurry. Neat triethylamine (Aldrich, 182 mg, 1.80 mmol) was added to form a tan solution. The reaction was stirred at 25° C. in a shaker block for 24 hr. The volatiles removed by rotary evaporator to give a brown oil. The product was purified by flash chromatography (silica gel: 10-45% ethyl acetate in hexanes). The product was recrystallized from hexanes to afford 67.0 mg (53%) of the title compound. 1H NMR (DMSO-d6) δ 0.49 (s, 3H), 0.90 (t, J=7.3 Hz, 3H), 1.25 (s, 3H), 1.26 (s, 3H), 1.28-1.33 (m, 2H), 1.37-1.46 (m, 1H), 1.57 (s, 9H), 1.57-1.70 (m, 3H), 2.01-2.10 (m, 1H), 2.62-2.67 (m, 2H), 2.74-2.83 (m, 1H), 2.83 (s, 3H), 3.05 (s, 3H), 3.33-3.39 (m, 1H), 8.49 (s, 1H).
