The 10 Step Outline:
3,4-dichlorobenzaldehyde
-->
1-(3,4-dichlorophenyl)-2-nitro-prop-1-ene
-->
1-(3,4-dichlorophenyl)-2-oxopropane
-->
1-(3,4-dichlorophenyl)-2-oxo-1-bromopropane
-->
Ketone protection with H+ and ethylene glycol, then treatment with NaCN, then deprotect spiro ketal with H+ to get the following ketone
-->
1-(3,4-dichlorophenyl)-1-cyano-2-oxopropane
-->
1-(3,4-dichlorophenyl)-1-cyano-N-formyl-2-aminopropane
plus anhydrous LAH and THF
-->
1-(3,4-dichlorophenyl)-1-carboxy-2-methylaminopropane
-->
1-(3,4-dichlorophenyl)-1-carbomethoxy-2-methylaminopropane
