Procedure
1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-(2-chloroethoxy)-7-methoxyquinazolin-4-yloxy)phenyl)urea (200 mg, 0.39 mmol) from the previous step was treated with piperidine (0.116 mL, 1.17 mmol), tetrabutylammonium iodide (0.39 mmol) and N,N′-diisopropylethylamine (0.78 mmol) in N,N′-dimethylformamide. The mixture was heated to 60° C. for 56 h and cooled to room temperature. Water was added and the solid filtered off and dried. The crude solid was purified by preparative HPLC (phenylhexyl reverse phase column) and the obtained solid triturated with water (10 mL) and drops of methanol, then filtered off and dried under high vacuum to afford 1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-methoxy-6-(2-(piperidin-1-yl)ethoxy)quinazolin-4-yloxy)phenyl)urea as a colorless solid (29 mg, 13%). 1H NMR (300 MHz, DMSO-d6) δ 9.80 (brs, 1H), 9.10 (brs, 1H), 8.55 (s, 1H), 7.64 (s, 1H), 7.59 (s, 1H), 7.37-7.42 (m, 2H), 7.26 (m, 1H), 6.96 (m, 1H), 6.48 (s, 1H), 4.26-4.30 (m, 2H), 3.99 (s, 3H), 2.72-2.76 (m, 2H), 2.40-2.50 (m, 4H), 1.48-1.52 (m, 4H), 1.37-1.39 (m, 2H), 1.30 (s, 9H); LC-MS (ESI) m/z 561 (M+H)+.
