Procedure

The mixture of the product of Example 1A (330 mg, 1 mmol), N-(2-ethynyl-phenyl)-2,2,2-trifluoro-acetamide (ref. Tetrahedron Lett. 1992, 33, 3915; 280 mg, 1.3 mmol), Pd2(dba)3 (Aldrich, 19 mg, 0.02 mmol) and K2CO3 (180 mg, 1.3 mmol) in DMSO (3 mL) was stirred at 40° C. under N2 for 2 hours. The reaction was monitored with TLC. After the reaction was complete, it was cooled down to room temperature and diluted with EtOAc (50 mL). It was then washed with brine (3×5 mL). The organic solution was concentrated and the title product was purified by preparative HPLC (Gilson, column, Symmetry® C-8 7 μm, 40×100 mm. Eluting Solvent, MeCN/H2O (with 0.2% v. TFA) (v. 90/10 to 10/90 over 20 min.) Flow rate, 75 mL/min., uv, 250 nm) as solid (113 mg, yield, 36%). 1H NMR (300 MHz, CD3OD) δ 1.43-1.57 (m, 1H), 1.62-1.89 (m, 2H), 2.01-2.15 (m, 1H), 2.16-2.23 (m, 1H), 2.73-3.03 (m, 5H), 3.28-3.40 (m, 1H), 4.51-4.58 (m, 1H), 6.97 (dt, J=8.8, 2.1 Hz, 2H), 7.03-7.17 (m, 2H), 7.36 (s, 1H), 7.37-7.42 (m, 1H), 7.57 (dt, J=8.8, 2.0 Hz, 2H), 7.81 (dt, J=7.8, 1.2 Hz, 1H) ppm. MS (DCI/NH3) m/z 319 (M+H)+.
