実験手順

A solution of 0.12 g (0.45 mmol) of 5-amino-8,9-difluoro-5-methyl-6,7-dihydro-5H-pyrido[3,2,1-ij]quinazoline-1,3-dione (Example 24i), 0.34 g (1.8 mmol) of (S)-3-pyrrolidinylcarbamic acid tert-butyl ester (J. Med. Chem., 1992; 35:1764), 0.2 g (2.0 mmol) of triethylamine and 7 mL of dimethyl sulfoxide is heated at 110° C. for 18 hours. The reaction is cooled to room temperature, diluted with 80 mL of ice and water and stirred at 5° C. for 1 hour. The resulting precipitate is removed by filtration, washed with water and dried in vacuo. The solid is chromatographed over flash grade silica gel (230-400 mesh) eluting with dichloromethane/ethanol (9:1) to give 0.14 g of the title compound, mp 98-100° C.
