Procedure

10.5 g of the product of Step A and 2.9 g of 4-dimethylamino-pyridine in 100 ml of tetrahydrofuran were refluxed for 7 hours 30 minutes and after cooling, the solvent was eliminated under reduced pressure. The residue was taken up in 100 ml of water and 10 ml of acetone. After separating, washing with water and drying at 70° C. under reduced pressure, 7.8 g of 1,3-dihydro-3-(1-methylethyl)-1-[(2-pyridinyl)-imino]-5-trifluoromethyl furo-[3,4-b]-quinolin-9-ol melting at 178°-180° C. were obtained.
