Reaktionsschritte
In a similar manner to Step 1 of Reference Example 2, indole-6-carboxylic acid (200 mg, 1.24 mmol) was dissolved in DMF (2 mL), and the solution was treated with EDCI (475 mg, 2.48 mmol), HOBT monohydrate (168 mg, 1.24 mmol) and 1-(tert-butoxycarbonyl)piperazine (461 mg, 2.48 mmol) to obtain 6-[4-(tert-butoxycarbonyl)piperazin-1-ylcarbonyl]indole (529 mg).
