The organic phase was washed with water, dried and evaporated to dryness. The residue was chromatographed over silica gel and was eluted with ethyl acetate to obtain 2-(1-chloroethyl)-4-hydroxy-N-(2-thiazolyl)-8-trifluoromethyl-3-quinoline-carboxamide which after crystallization from ether melted at ≈190° C.
