Procedure

To a 20 mL scintillation vial was added the product from Example 28 (30 mg, 0.085 mmol), tert-butyl 2-amino-2-methylpropanoate (15.0 mg, 0.088 mmol), and N,N-dimethylformamide (0.85 mL) followed by O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (39.0 mg, 0.102 mmol) and diisopropylethylamine (30 μL, 0.176 mmol). Following 4 hours of stirring, the solvent was evaporated and the residue purified over RP-HPLC to afford the title product. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.01-1.16 (m, 2 H), 1.26-1.31 (m, 6 H), 1.3-5 (s, 9 H), 1.40-1.53 (m, 2 H), 1.68-1.77 (m, 1 H), 1.77-1.90 (m, 4 H), 1.93-2.02 (m, 2 H), 8.01 (s, 1 H), 13.98 (s, 1 H): MS (ESI) min 494 [M+H]+.
