2,2-dimethylpropylurea

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

Procedure: N-neopentylurea (13.0 g, 0.1 mol) and ethyl cyanoacetate (10 ml) were heated in 4N NaOEt (100 ml) for 4 hours under reflux. The reaction mixture was evaporated to dryness, the residue treated with water (100 ml) and then acidified with AcOH to pH 4–5 to form a colorless precipitate. Yield: 11.2 g (59%). under reflux The reaction mixture was evaporated to dryness the residue treated with water (100 ml) to form a colorless precipitate

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