Procedure

To a stirred mixture of 2 parts of intermediate 21, namely 3,4-dihydro-6-(1-hydroxy-ethyl)-2(1H)-quinolinone in 8.9 parts of tetrahydrofuran were added 1.62 parts of thionyl chloride. Stirring at room temperature was continued overnight. The reaction mixture was evaporated and the residue was co-evaporated with methylbenzene, yielding 2.3 parts (93.4%) of 6-(1-chloroethyl)-3,4-dihydro-2(1H)-quinolinone hydrochloride (interm. 36).
