Помогите получить из ацетоуксусного эфира диметилуксусную кислоту.

CH3-CO-CH2-COOEt + NaOEt ----> CH3-CO-CHNa-COOEt + EtOH

CH3-CO-CHNa-COOEt + CH3Br ----> CH3-CO-CH(CH3)-COOEt + NaBr

CH3-CO-CH(CH3)-COOEt + NaOEt ----> CH3-CO-C(CH3)(Na)-COOEt + EtOH

CH3-CO-C(CH3)(Na)-COOEt + CH3Br ----> CH3-CO-C(CH3)2-COOEt + NaBr

CH3-CO-C(CH3)2-COOEt --(NaOH конц., t)--> CH3COONa + (CH3)2CH-COONa + EtOH

(CH3)2CH-COONa --(HCl, -NaCl)--> (CH3)2CH-COOH
