LHMDS (1.40 mL, 1.0 M in THF, 1.40 mmol) was added slowly to a stirred solution of 2-hydroxy-3-methoxy-N-(5-methylpyridin-2-yl)propanamide (200 mg, 0.951 mmol) in anhydrous THF (5 mL). The reaction mixture was kept at ambient temperature for 10 minutes, and a solution of 4-chloro-1-(2-chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidine (265 mg, 1.00 mmol) in anhydrous THF (3 mL) was added. The reaction mixture was heated at 50° C. for ½ hrs (another 3 equivalents of LHMDS were added and the reaction heated for 18 hrs at 50° C. in example 49). Water and EtOAc were added, and the two phases were separated. The organic phase was washed with water, dried over MgSO4 and concentrated in vacuo. The residue was purified with column chromatography (silica gel, eluting with DCM/EtOAc:2/1) to give the title compound as a colourless solid (323 mg), 1H NMR (500 MHz, CDCl3) δ 8.67 (br s, 1H), 8.62 (s, 1H), 8.48 (s, 1H), 8.18 (d, 1H), 8.12 (s, 1H), 7.65 (d, 1H), 7.52 (m, 4H), 6.13 (t, 1H), 4.14 (m, 2H), 4.06 (m, 1H), 3.49 (s, 3H), 2.32 (s, 3H), HRMS: calcd for (M+H+) C21H2035ClN6O3: 439.1285. Found: 439.1287.
