(3-chlorophenyl)methylurea

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

Procedure: 3.76 g of 98% cyanoacetic acid and 14 ml of acetic anhydride were heated for 1 hour at 65° C. A solution of 7.73 g of (3-chlorobenzyl)urea in 55 ml THF was added and the mixture kept for 4 hours at 65° C. The THF was removed in vacuo and the residue diluted with 50 ml of toluene. The solid was collected and washed to give the title compound (8.94 g) as a white solid. The THF was removed in vacuo the residue diluted with 50 ml of toluene The solid was collected washed

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

Procedure: 3.22 g of sodium cyanate was added to a solution of 5.50 ml of 3-chlorobenzylamine in 40 ml of water and 40 ml of THF followed by dropwise addition of 48.6 ml of 1N HCl. After 3 days, the mixture was evaporated to dryness, the residue extracted with hot THF and the filtrate again evaporated to dryness. The residue was suspended in 180 ml of diethyl ether and the solid collected to give the title compound (7.91 g) as a white solid. the mixture was evaporated to dryness the residue extracted with hot THF the filtrate again evaporated to dryness the solid collected
