実験手順

A stirred solution of (1-(5-tert-butyl-isoxazol-3-yl)-3-{3-[7-(3-chloro-propoxy)-6-methoxy-quinazolin-4-yloxy]-phenyl}-urea from Example 27B (102 mg, 0.194 mmol), (S)-3-pyrrolidinol (51 mg, 0.582 mmol), N,N-diisopropylethylamine (75 mg, 0.582 mmol) and tetrabutylammonium iodide (71 mg, 0.194 mmol) in dry N, N-dimethylformamide (5 mL) was heated at 60° C. for 20 h. After cooling to room temperature, the reaction mixture was partitioned between water (50 mL) and ethyl acetate (50 mL) and the organic layer was separated, washed with brine (50 mL), dried (MgSO4) and concentrated under reduced pressure. The residue was purified by preparative HPLC (using a phenyl-hexyl reverse phase column, eluted with gradient of solvent B=0.05% HOAC/CH3CN and solvent A=0.05% HOAc/H2O). The combined fractions were washed with saturated aqueous NaHCO3 and the aqueous layer extracted with a mixture of 20% methanol in dichloromethane (2×50 mL). Concentration under reduced pressureafforded (S)-1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-(3-(3-hydroxypyrrolidin-1-yl)propoxy)-6-methoxyquinazolin-4-yloxy)phenyl)urea as a colorless solid (16 mg, 14%). 1H NMR (300 MHz, CDCl3) δ 8.59 (brs, 1H), 7.68 (brs, 1H), 7.52-7.55 (m, 2H), 7.26-7.35 (m, 4H), 6.95 (m, 1H), 6.11 (s, 1H), 4.34-4.40 (m, 3H), 4.04 (s, 3H), 3.00-3.20 (m, 2H), 2.84 (m, 1H), 2.67-2.68 (m, 2H), 2.50 (m, 1H), 2.10-2.30 (m, 3H), 1.80 (m, 1H), 1.51 (m, 1H), 1.26 (s, 9H); LC-MS (ESI) m/z 577 (M+H)+.
