실험 절차

Refer to 32(a) using 4-bromo-2-butenoic acid as the alkylating agent. Preparation of 2-(4-carboxy-n-butyl) indole: Refer to Example 3 using methyl adipyl chloride as the acid chloride. The methyl ester was hydrolyzed in the cyclization workup to provide the product carboxyindole. In the alternative, refer to Example 32b) using 2-(4-carboxy-3-buten-1-yl) indole as the starting material.
