Reaction Steps

To a solution prepared by dissolving 100 mg of 5-bromofuran-2-carboxylic acid, 145 mg of (E) type 4-aminoadamantane-1-carboxylic acid amide (prepared from Preparation Example 1), and 202 mg of TBTU in MC was added dropwise 0.2 mL of DIEA and then stirred at room temperature for 4 hours. The reaction solution was washed with a 1N solution of HCl and a 1N solution of NaOH, respectively, and then washed again with brine. The resulting organic solution was dried over MgSO4 and after filtration, was distilled under a reduced pressure. The compound thus obtained was purified via recrystallization by using MeOH and ether to produce 150 mg of a white solid product.
