Versuchsvorschrift

Compound 1-7 (75 mg, 0.21 mmol) was combined with 2-chloro-6-fluoroquinazoline 1-8 (39 mg, 0.21 mmol; see example 1-D), triethylamine (30 uL, 0.21 mmol), and potassium carbonate (296 mg, 2.1 mmol) in toluene (2 mL) and heated in a sealed tube to 130° C. overnight. The reaction was concentrated in vacuo and the residue purified by reverse phase preparative chromatography on a C-18 column (5 to 75% acetonitrile in water with 0.1% TFA buffer). The clean fractions were combined and made basic with 20% sodium carbonate solution. This was extracted with ethyl acetate two times and the combined organics washed with brine and dried with sodium sulfate. Concentration in vacuo gave the titled compound as a solid. Data for 1-9: LC/MS: m/z (M+Na)=460.2 found; 460.5 calculated.
