Procedure
##STR6## 4 mmol of 3-(3-nitrobenzylidene)-4-oxo-butyrolactone (E/Z mixture) and 4.4 mmol of methyl 3-aminocrotonate are suspended in 5 g of tert.-butanol, and the suspension is stirred for 3 hours at 30° C. It is evaporated down at room temperature in a rotary evaporator, and the residue is crystallized with a small amount of methanol. M.p.: 147°-149° C. (from methanol):
