Pyridine → n-(Benzoyl)-3-hydroxylmethyl-n'-[(7-methoxycarbonyl-indol-3-yl)-oxoacetyl]-piperazine

Participants

Reaction Steps

To a stirred solution of 3-hydroxylmethyl-benzoylpiperazine XLIX (8.0 mg, 0.036 mmol) in acetonitrile (5 ml) was added BSTFA (8.1 mg, 0.036 mmol). After stirring for 30 minutes at room temperature, (7-methoxycarbonyl-indol-3-yl)-oxoacetyl chloride (8.1 mg, 0.036 mmol) and pyridine (0.5 ml) were added. The reaction was stirred for another 2 hours at room temperature. Concentration under vaccum provided a residue, which was then purified by Shimazu HPLC purification system to give 2 mg of N-(benzoyl)-3-hydroxylmethyl-N′-[(7-methoxycarbonyl-indol-3-yl)-oxoacetyl]-piperazine (Example 98).
