Versuchsvorschrift

A suspension of 1-(3-{[2-(1H-1,2,4-triazol-3-ylthio)ethyl]oxy}phenyl)methanamine obtained in Reference Example 3 (300 mg, 0.999 mmol), ethyl 6-cyano-4-oxo-3,4-dihydroquinazoline-2-carboxylate obtained in Reference Example 51 (200 mg, 0.822 mmol) and diisopropylethylamine (0.180 mL, 1.05 mmol) in ethanol (2 mL) was stirred at 90° C. for 2 days. The reaction solvent was evaporated under reduced pressure, and the residue was purified by preparative HPLC (GILSON 215LIQUD HANDLER, 322PUMP, UV/VIS-156, SHISEIDO CAPCELL PACK C-18 UG120 S-5 (20 mmφ×50 mm), mobile phase: distilled water (containing 0.1% trifluoroacetic acid)/acetonitrile (containing 0.1% trifluoroacetic acid), gradient: distilled water/acetonitrile=90/100/100, time: 10 min, flow rate: 25 mL/min, detection wavelength: 220 nm), and the obtained crude crystals were recrystallized from ethanol to give the title compound as a white powder (97.4 mg, 26%).
