Procedure

To a solution of CDI (100 mg, 0.370 mmol) in dry DCM (1.0 mL) was added 3-tert-butyl-1-p-tolyl-1H-pyrazol-5-amine (85 mg, 0.370 mmol), portionwise, over 20 min and the resulting solution maintained at RT for 2.5 hr. A portion of this solution (0.70 mL) was added to a solution of (R)—N-(4-(4-aminonaphthalen-1-yloxy)pyridin-2-yl)-3-(dimethylamino)pyrrolidine-1-carboxamide (100 mg, 0.255 mmol) in DCM (1.0 mL) and the mixture was maintained at RT for 18 hr. The reaction was quenched by the addition of MeOH (3.0 mL) and the mixture was evaporated in vacuo. The residue was purified by flash column chromatography (SiO2, 4 g, [5% NH3 (7M in MeOH) in DCM] in DCM, 0-100%, gradient elution) to afford the title compound, Example 54, as a brown glass (52 mg, 30%); Rt 4.92 min (Method 1 basic); m/z 647 (M+H)+ (ES+); 1H NMR (400 MHz, DMSO-d6) δ: 1.28 (9H, s), 1.61 (1H, m), 1.98 (1H, m), 2.12 (6H, s), 2.39 (3H, s), 2.58 (1H, m), 3.03 (1H, m), 3.25 (1H, m), 3.49 (1H, m), 3.58 (1H, m), 6.41 (1H, s), 6.60 (1H, dd), 7.30 (1H, d), 7.37 (2H, d), 7.44-7.47 (3H, overlapping m), 7.56 (1H, m), 7.64 (1H, m), 7.83 (1H, d), 7.95 (1H, d), 8.08 (1H, d), 8.10 (1H, d), 8.70 (1H, s), 8.79 (1H, s), 9.12 (1H, s)
