    摘要: 4-(Amino-(polycarbon-lower-alkyl)-amino)-2-halobenzyl alcohols and lower-alkyl ethers thereof have schistosomacidal activity. The benzyl alcohols are prepared: by reduction of the corresponding benzaldehydes or lower-alkyl benzoates; by microbiological oxidation of the corresponding 4-substitutedamino-2-halotoluenes; or, for the compounds where polycarbonlower-alkyl is ethylene, by reducing the corresponding loweralkyl 4-(aminoacetylamino)-2-halobenzoates or by reducing the corresponding 4-(aminoacetylamino)-2-halobenzyl alcohols. The ethers are prepared by heating the benzyl alcohols with a loweralkanol in the presence of an acid.
