実験手順

To a solution of 2-methoxybenzhydrazide (0.040 g, 0.238 mmol) and compound 7 (preparation described in scheme 2 example 1c, step 7) (0.11 g, 0.238 mmol) in dichloromethane (2 mL) under nitrogen was added EDC (0.046 g, 0.238 mmol) followed by DMAP (5.81 mg, 0.048 mmol). The reaction was left to stir for 16 hours at room temperature. Another portion of EDC (20 mg, 0.104 mmol) was added and the reaction continued for 4 hours. The solvent was then removed on the rotary evaporator and the crude purified by silica gel column chromatography with a Biotage 12M column and a gradient of 0-5% methanol in dichloromethane to give compound 16 as a yellow crust (73.7 mg, 51%). LRMS (ESI): calc. 610.2; found 511.2 (MH-Boc)+, 633.3 (MNa)+.
