3-oxobutanal

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

Procedure: Starting from 2-amino-2-(p-methoxyphenyl)acetonitrile and acetylacetaldehyde, the open-chain intermediate product is prepared, boiling at 180° C./0.03 mm Hg. Overall yield of the title compound: 44%, m.p. 198°-200° C. (from diethyl ether). the open-chain intermediate product is prepared
