Reaction Steps

A solution of ethyl 2-methylacetoaceate (1-004-01) (115.34 g) and benzylamine (85.73 g) in toluene (1.6 L) was azeotropically dehydrated in an oil bath at 145° C. for 8 h under nitrogen atmosphere. Benzylamine was added to the reaction mixture and the reaction mixture was dehydrated again. After 6 h, the reaction mixture was distilled under atmospheric pressure to remove about 600 mL of the solvent, and evaporated under reduced pressure to give ethyl 3-benzylamino-2-methylcrotonate (1-004-02) (195.66 g).
