General procedure: To a mixture of 33 (126.3 mg,0.295 mmol) and 1H-pyrazole (24.1 mg, 0.353 mmol) in DMF(4 mL) was added K2CO3 (48.8 mg, 0.353 mmol). The mixturewas stirred at 90C for 30 min and then poured into water.The mixture was extracted with EtOAc, washed with water and saturated aqueous NaCl, dried over anhydrous Na2SO4and concentrated in vacuo. The residue was purified bycolumn chromatography (silica gel, hexane-ethyl acetate,19 : 1 to 0 : 100) to afford 14 (102 mg, 0.222 mmol, 75%) as awhite solid after trituration with hexane-ethyl acetate (5 : 1).1H-NMR (300 MHz, DMSO-d6) delta: 1.02 (3H, s), 1.36 (3H,s), 4.86 (1H, d, J=8.3 Hz), 5.34 (1H, s), 6.75-6.81 (1H, m),7.23-7.33 (2H, m), 7.48-7.58 (2H, m), 7.76 (1H, d, J=7.5 Hz),8.05 (1H, d, J=1.5 Hz), 8.46 (1H, s), 9.02-9.14 (2H, m), 9.37(1H, d, J=7.5 Hz). MS (ESI/APCI) m/z 461.1 [M+H]+. HPLCpurity: 100%. mp 241C.
