Procedure

SLA 09052A was prepared in accordance with method D using thiophene-3-carbaldehyde (0.768 mL, 5.35 mmol), KOH (0.273 mg, 4.86 mmol) in methanol (5 mL) and 2-isocyano-1-morpholinoethanone SLA 07118 (0.75 g, 4.86 mmol). The solution was stirred for 2 h at 0° C. After work-up the residue was purified by column chromatography (florisil, EtOAc). After evaporation and drying, trans-(4,5-dihydro-5-(thiophen-3-yl)oxazol-4-yl)(morpholino)methanone SLA 09052A (0.327 g, 25% yield) was obtained as a yellow oil.
