Procedure

7-(Phenylthiocarbamoylamino)-4-chloro-3-(2-bromoethoxy)isocoumarin was prepared from the reaction of phenyl isothiocyanate with 7-amino-4-chloro-3-(2-bromoethoxy)isocoumarin, yield 59%, m.p. 157°-158° C.; mass spectrum m/e 361 (m+ -PhNH+1). Anal. Calc.: C, 48.36; H, 3.39. Found: C, 48.26; H, 3.40. The bromoethoxy compound was then reacted with thiourea by the same procedure to give the final product, yield 32%, mass spectrum (FAB+) m/e 449 (M+ -Br).
