Versuchsvorschrift
In a similar manner as in Production Example 16, step 1, {[2-(acetylamino)-1,3-thiazol-4-yl]methyl}(triphenyl)phosphonium chloride (12.03 g, 26.56 mmol) and 5-(1,3-dioxolan-2-yl)-4-methylthiophene-2-carbaldehyde (3.51 g, 17.7 mmol) were condensed to give N-(4-{2-[5-(1,3-dioxolan-2-yl)-4-methylthiophen-2-yl]vinyl}-1,3-thiazol-2-yl)acetamide (4.450 g, 13.23 mmol, yield 74.7%) as a yellow solid.
