実験手順

NaH (30 mg of 60% in mineral oil, 0.77 mmol) was added to anhydrous DMF (2.0 mL) followed by pyrid-4-one (79 mg, 0.83 mmol). The mixture was stirred 40 minutes at 22° C. until all solids dissolved and the evolution of H2 ceased. The title product of Example 34 (120 mg, 0.28 mmol) and tetrabutylammonium iodide (15 mg) were added and the reaction mixture was stirred at 22° C. for 7 days under N2. Additional pyrid-4-one (79 mg) and NaH (30 mg of 60%) were dissolved in DMF (2 mL) and the solution was added to the reaction mixture. After another 4 days stirring the mixture was partitioned between CHCl3 and brine. The organic extracts were dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by flash chromatography on silica utilizing 10% methanol/CH2Cl2 to afford 65 mg of the free base of the title product which was converted to the mono-hydrochloride salt according to the procedure described for Example 28 (66 mg; M.P. 240°-248° C. (dec); LC-MS: 457 (MH+); anal. RP-HPLC RT: 3.23 min)
