実験手順

To a solution of Example 52 (13.8 mg, 0.023 mmol) in MeCN (0.5 ml) were successively added AcOH (0.003 ml, 0.046 mmol), formaldehyde (37% in water, 0.003 ml, 0.046 mmol) and NaBH(OAc)3 (9.7 mg, 0.046 mmol) at RT. The reaction mixture was stirred at RT for 2 h then directly subjected to purification by reverse phase prep-HPLC (Waters system) to yield the title compound (TFA salt, 7.4 mg, 0.010 mmol, 44%) as a colorless solid. HPLC: AtRet=2.01 min; LC-MS: m/z 618.4 [M+H]+.
