Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 5-fluoro-2-morpholino aniline (6 g) and thiophosgene (5.2 g) in dioxan (20 ml) and water (40 ml) was stirred at 0° C. for 15 minutes and at room temperature for one hour to yield a residue which was extracted with dichloromethane to give an oil which was purified by chromatography on a silica gel column (mesh 100-200) using a 1:9 mixture of ethylacetate and hexane as eluant to give 5-fluoro-2-morpholinophenyl isothiocyanate as an oil. to yield a residue which was extracted with dichloromethane to give an oil which was purified by chromatography on a silica gel column (mesh 100-200) a 1:9 mixture of ethylacetate and hexane as eluant
