The same procedure was employed as for amine 50, using 3-amino-2,2-dimethylpropanamide, to provide the product 51. The material was purified by prep HPLC (C18 30×100 mm column, 5-60% CH3CN/10 mM aqueous ammonium formate, 45 mL/min) and lyophilized to give the formate salt the product as a white solid. 1H NMR (400 MHz, MeOH-d4) δ ppm 7.11-7.21 (m, 3 H), 7.06 (d, J=8.1 Hz, 2 H), 6.88 (m, J=8.3 Hz, 2 H), 4.39 (d, J=9.3 Hz, 1H), 4.05-4.16 (m, 3 H), 3.94 (s, 2 H), 3.35-3.53 (m, 3 H), 3.23 (t, J=6.9 Hz, 2 H), 3.07 (s, 2 H), 2.20 (s, 3 H), 2.16-2.24 (m, 2 H), 2.14 (s, 3 H), 1.33 (s, 6 H); MS (ES+) [M+H]+=533.
