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

Procedure: According to the Scheme 1 Step 1: A mixture of 4-chlorobenzylamine (10.0 g, 71 mmol), cyanoacetic acid (6.13 g, 72 mmol), HOBt (11 g, 72 mmol), EDCI.HCl (20 g, 106 mmol) in 100 mL of dioxane was stirred for 3 h at room temperature. The solvent was removed under vacuum and 300 mL of DCM was added. The organic layer was successively washed with 2×100 mL of water, 2×50 mL of a solution 1N of NaOH, 4×100 mL of water until neutral pH. The organic layer was dried over Na2SO4, filtered and concentrated to afford N-(4-chlorobenzyl)-2-cyanoacetamide 1(A) (13.12 g, 89%) as a brown solid. The solvent was removed under vacuum and 300 mL of DCM was added The organic layer was successively washed with 2×100 mL of water, 2×50 mL of a solution 1N of NaOH, 4×100 mL of water until neutral pH The organic layer was dried over Na2SO4 filtered concentrated
