Procedure

(1-(5-Tert-butyl-isoxazol-3-yl)-3-{3-[7-(3-chloro-propoxy)-6-methoxy-quinazolin-4-yloxy]-phenyl}-urea (210 mg, 0.4 mmol) from Example 27B was treated with (R)-(+)-3-pyrrolidinol (65 μL, 0.8 mmol), tetrabutylammonium iodide (148 mg, 0.4 mmol) and N,N′-diisopropylethylamine (69 μL, 0.4 mmol) in N,N′-dimethylformamide (4 mL). The mixture was stirred at 50° C. for 5 h. After cooling to room temperature water (4 mL) was added and the precipitating solid filtered off and dried. The solid residue was purified by preparative HPLC (phenylhexyl reverse phase column). The obtained solid was triturated with water to give (R)-1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-(3-(3-hydroxypyrrolidin-1-yl)propoxy)-6-methoxyquinazolin-4-yloxy)phenyl)urea (37.76 mg, 16%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.60 (s, 1H), 9.10 (s, 1H), 8.55 (s, 1H), 7.58-7.56 (m, 2H), 7.40-7.38 (m, 2H), 7.25 (d, 1H), 6.98 (d, 1H), 6.48 (s, 1H), 4.70 (s, 1H), 4.31-4.20 (m, 3H), 3.99 (s, 3H), 3.32 (s, 1H), 2.81-2.69 (m, 2H), 2.40-2.19 (m, 3H), 2.10-1.98 (m, 3H), 1.67-1.4 (m, 1H), 1.27 (s, 9H); LC-MS (ESI) m/z 577 (M+H)+.
