Procedure for the preparation of 3-aminoacrylic acid esters: Procedure for the preparation of 3-aminoacrylic acid esters. Englaender, Fritz; El-Chahawi, Moustafa; Vogt, Wilhelm (Dynamit Nobel A.-G., Fed. Rep. Ger.). Ger. Offen. DE 3531067 A1 5 Mar 1987, 3 pp. (Germany) CODEN: GWXXBX. CLASS: ICM: C07C101-28. ICS: C07D295-14. APPLICATION: DE 85-3531067 30 Aug 1985. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) R1R2NCH:CR3CO2R4 [I; R1, R2 = H, C1-8 alkyl, alkenyl, Q (Q = mono- or polycyclic isocyclic or heterocyclic ring), (CH2)nQ1 [n = 0-5, Q1 = Q, (un)substituted aryl or heteroaryl]; R3 = H, C1-8 alkyl, isocyclic or heterocyclic ring, aryl; NR1R2 = heterocyclyl optionally with an addnl. N and contg. 0-2 double bonds; R4 = C1-8 alkyl, isocyclic or arom. ring] were prepd. 64124-13-6 and 924-99-2 are also in the experiment. by adding MOCH:CR3CO2R4 (M = alkali metal) to an aq. soln. of R1R2NH×HX (X = anion inorg. or org. acid). Me2NH×HCl in H2O was treated with NaOCH:CHCO2Et to give Me2NCH:CHCO2Et in 74.8% yield and 99.7% purity. .
