실험 절차

The product of Example 9A (120 mg, 0.5 mmol) was coupled with 2-(1-benzothiophen-5-yl-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (Maybridge, 260 mg, 1.0 mmol) according to the procedure of Example 26B. The title product was purified by preparative HPLC (column: Xterra™ RP-18, 5 μm, 30×100 mm. eluting solvent, MeCN/H2O (with 0.1% v. TFA), (v. 90/10 to 10/90 over 20 min.) flow rate, 40 mL/min., uv, 254 nm) to provide a solid (157.3 mg, yield, 70%). 1H NMR (300 MHz, CD3OD) δ 1.92-2.25 (m, 3H) 2.35-2.49 (m, 1H) 2.63-2.71 (m, 1H) 3.35-3.56 (m, 5H) 3.95-4.06 (m, 1H) 5.55-5.62 (m, 1H) 7.37 (d, J=9.16 Hz, 1H) 7.50 (dd, J=5.43, 0.68 Hz, 1H) 7.68 (d, J=5.43 Hz, 1H) 7.96-8.02 (m, 1H) 8.05-8.10 (m, 1H) 8.22 (d, J=9.49 Hz, 1H) 8.45 (d, J=1.70 Hz, 1H) ppm.
