5-((4-(4-Amino-3-fluorobenzoyl)piperazin-1-yl)methyl)-N-tert-butylfuran-2-carboxamide (Example 3; 0.05 g, 0.124 mmol) and N,N-diisopropylethylamine (0.028 mL) were dissolved in dichloromethane (5 mL). Bis(trichloromethyl)carbonate (0.014 g, 0.046 mmol) was added dropwise and the reaction was left to stir for 30 minutes. N,N-diisopropylethylamine (0.094 mL) was added to the reaction followed by 2-methylpropan-1-amine (0.018 g, 0.248 mmol, 0.025 mL) and the reaction was stirred for a further 2 hours. The reaction mixture was washed with water and flushed through a hydrophobic frit. The organic phase was concentrated under vacuum and purified by basic reverse phase HPLC to afford the title compound (5 mg).
