Participants

Reaction Steps

Compound 125 (300.0 mg) obtained in Example 125 was dissolved in a mixed solvent of N,N-dimethylformamide and tetrahydrofuran (1:1), and methyl iodide (93.6 mg) and then sodium hydride (26.4 mg, 60% mineral oil dispersion) were added thereto, followed by stirring for 1.5 hours. The reaction solution was subjected to partitioning between chloroform and water, and the organic layer was successively washed with water and a saturated saline, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained crude crystals were washed with chloroform and recrystallized from a mixed solvent of ethanol, N,N-dimethylformamide, and water to give Compound 126 (249.7 mg).
