To an ice cooled solution of Boc-Aze-OH (0.194 g, 0.96 mmol) in 5 mL of DMF was added TBTU (0.50 g, 9.6 mmol). After 30 min another solution, comprising 4-aminomethyl-2-fluorobenzonitrile (0.17 g, 0.81 mmol; see step (y) above) and diiisopropylethyl amine (0.326 g, 2.53 mmol) in 7 mL of DMF was added. The resulting solution was stirred overnight at room temperature. The solvent was evaporated and the product was purified by preparative RPLC using CH3CN:0.1M NH4OAc (50:50). Freeze-drying gave 0.237 g (74%) of the desired sub-title compound.
