실험 절차

The title product from Example 34 (110 mg, 0.253 mmol) in DMF (2 mL) was treated with imidazole (172 mg, 2.53 mmol) at 110° C. for 48 hours. The reaction mixture was partitioned between CHCl3 and saturated aqueous NaHCO3. The organic extracts were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The crude product (119 mg) was chromatographed on silica using 10% methanol/CH2Cl2 to provide 85 mg of pure title product as its free base. This white solid was dissolved in a minimum volume of CHCl3, and titrated with 2 equivalents of 1M HCl in ether to precipitate the title product as a white solid (95 mg; 75%; M.P. 220°-227° C. (dec); LC-MS: 430 (MH+); anal. RP18-HPLC RT: 3.75 min.).
