Procedure

To a stirred suspension of [5-(4-amino-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-2-yl]-[4-(2-pyrrolidin-1-yl-ethoxy)-phenyl]-amine (0.05 g, 0.121 mmol) and MP-CNBH3 (180 mg, 0.360 mmol) in methanol (1 ml) was added acetic acid (6 μl, 0.121 mmol) followed by 3-chlorobenzaldehyde (15 μl, 0.133 mmol). The mixture was stirred for 18 hours at room temperature, then filtered and concentrated in vacuo. The product was purified by preparatory HPLC to yield the desired product. RT: 3.09 min, MI: 539, Method: 2; 1H NMR (DMSO, 300 MHz): 8.47 (s, 1H), 7.90 (2H, d), 7.50-7.27 (m, 8H), 6.92 (d, 1H), 6.84 (d, 2H), 6.74 (d, 2H), 4.42 (s, 2H), 4.30 (t, 2H), 3.37 (t, 2H), 3.26 (s, 4H), 2.03 (s, 4H).
