methyl 2-(4-chloroanilino)acetate

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

Procedure: Three grams (15 mmol) of methyl 4-chlorophenylaminoacetate were dissolved in 40 ml of benzene, and 2.2 ml (15 mmol) of 4-chlorobenzenesulfonyl isocyanate were added to the resultant solution, followed by stirring for 1 hour. Crystals formed were collected by filtration to obtain N-(4-chlorobenzenesulfonyl)-N'-(4-chlorophenyl)-N'-methoxycarbonylmethylurea (6.1 g) as white crystals. Crystals formed were collected by filtration

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