Reaktionsschritte

A solution of 86 g of crotonic acid (1 mole) and ethanol-amine (1 mole) in pyridine (200 ml) is refluxed for 2-3 hours and subsequently cooled. The resulting produce is filtered and recrystallized to yield the title compound having m.p. 178°-180° C. (compound 1.1, Table 1). Following analogous procedure, the compounds 1.2-1.7, 1.10, 1.11, and 1.13-1.15 set forth in Table 1 are obtained.
