Abstract
PURPOSE: To prepare the title compound useful as an anthelmintic agent, in high yield, by halogenating an isothioureide derivative easily obtained from a novel thiourea derivative, and subjecting the product to the condensation ring-closure in the presence of an alkali in one step.
CONSTITUTION: The compound IV is prepared by the following steps: (1) reaction of a compound V with a thiocyanate in the presence of an acylating agent to afford a novel compound I (R is H, halogen, NO2; R' is acyl); (2) hydrolysis of the compound I with an alkali to afford the compound II; (3) reaction of the compound II with a compound of formula XCH2CH2Y (X is halogen; Y is OH, halogen) to give a compound III; (4) conversion of the compound III to a halogen derivative with a halogenation agent (pref. thionyl chloride), and (5) the condensation cyclization reaction of the halogen derivative in the presence of an alkali at 40W100°C.
