Reaction Steps

To (2-Chloro-6-piperidin-1-yl-quinazolin-4-yl)-(5-cyclopropyl-2H-pyrazol-3-yl)-amine (80 mg, 0.217 mmol) in NMP (1 mL) was added 6-Amino-3-oxo-2,3-dihydro-indazole-1-carboxylic acid tert-butyl ester (65 mg, 0.26 mmol) and heated to 90° C. for 12 hr in a sealed tube. Solution was poured into sat. NaHCO3, resulting in a brown solid. The dried solid was taken up in 5 ml of methylene chloride and treated with 5 mL of TFA for 6 hr. The reaction was evaporated and the title compound was isolated by preparative HPLC to give a yellow solid (47,5 mg). HNMR (500 MHz, dmso); δ11.45 (1H, bs), 10.45 (1H, bs), 8.0 (1H, s), 7.70 (1h, m), 7.6 (1H, m), 7.5 (1H, m), 7.4 (1H, s), 7.1 (1H, m), 6.25 (1H, bs), 3.3 (4H, bs), 2.80–2.55 (7H, m), 0.80 (2H, m), 0.40 (2H, m); HPLC tr=3.51 min (10% to 90% MeCN over 8 min, total time 12 min, 3×150 mm C18 column) FIA m/e 482.5 (M+H), 480.2 (M−H).
