Procedure

The intermediate 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-(3-chloropropoxy)-7-methoxyquinazolin-4-yloxy)phenyl)urea (200 mg, 0.38 mmol) from Example 21B was treated with thiomorpholine-1,1-dioxide (154 mg, 1.14 mmol), tetrabutylammonium iodide (140 mg, 0.38 mmol) and N,N′-diisopropylethylamine (135 μL, 0.76 mmol) in N,N′-dimethylformamide (2 mL). The mixture was heated to 60° C. for 56h and cooled to room temperature. Water was added and the solid filtered off and dried. The crude solid was purified by preparative HPLC (Phenomenex phenylhexyl reverse phase column) and the obtained solid triturated with water and drops of methanol, then filtered off and dried under high vacuum to afford 1-(5-tert-butyl-isoxazol-3-yl)-3-(3-{6-[3-(1,1-dioxo-thiomorpholin-4-yl)-propoxy]-7-methoxy-quinazolin-4-yloxy}-phenyl)-urea (46.40 mg, 20%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 9.62 (bs, 1H), 9.04 (bs, 1H), 8.56 (s, 1H), 7.57 (d, 2H), 7.40-7.37 (m, 2H), 7.25 (d, 1H), 6.97 (d, 1H), 6.47 (s, 1H), 4.25-4.21 (m, 2H), 4.00 (s, 3H), 3.34 (bs, 4H), 2.93 (bs, 4H), 2.68-2.64 (m, 2H), 1.99-1.96 (m, 2H), 1.18 (s, 9H); LC-MS (ESI) m/z 625 (M+H)+.
