Title:
METHOD FOR PRODUCING NITROGEN-CONTAINING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/074411
Kind Code:
A1
Abstract:
Provided is an efficient and economical method for producing a nitrogen-containing compound. In this method for producing a compound represented by the formula R3C(O)CH=CHNR1R2, a six-fold molar excess of a compound represented by the formula NR1R2C(O)H is reacted with a compound represented by formula (4), to obtain a reaction mixture of the compound represented by formula (4) and the compound represented by the formula NR1R2C(O)H, and a basic compound is used to react the reaction mixture with a compound represented by the formula R3C(O)CH3 (in the formulae, X represents a halogen atom, and R1, R2, and R3 each independently represent a C1-6 alkyl group).
