実験手順

To a solution of 87 mg of the resultant compound from Example 218 in 1 ml of DMF was added 0.028 ml of 3-aminomethylpyridine. After 18 hours, the solvent was removed in vacuo and the residue was dissolved in 1 ml of methanol and 0.05 ml of chlorotrimethylsilane was added. After 0.5 hour, the solvent was removed in vacuo, neutralized with sodium bicarbonate solution and extraction with ethyl acetate (2×25 ml). The organic solution was dried and concentrated. Purification by silica gel column chromotography provided 35 mg of desired product. 1H NMR (CD3OD): δ 1.60 (t, 2H), 2.60-2.80 (m, 4H), 3.70 (m, 1H), 4.00 (m, 1H), 4.10 (m, 1H), 4.25-4.35 (m, 4H), 7.10-7.25 (m, 10H), 7.35 (m, 2H), 7.60 (m, 2H), 8.40 (m, 4H). Mass spectrum: (M+H)+ =553.
