SLA 09052B was prepared in accordance with method D using thiophene-3-carbaldehyde (0.778 mL, 5.43 mmol), KOH (0.273 mg, 4.94 mmol) in methanol (5 mL) and 2-isocyano-1-(piperidin-1-yl)ethanone SLA 07116B (0.75 g, 4.94 mmol). The solution was stirred for 2 h at 0° C. After work-up (without any further purification) and drying trans-(4,5-dihydro-5-(thiophen-3-yl)oxazol-4-yl)(piperidin-1-yl)methanone SLA 09052B was obtained as a yellow oil (1.29 g, 99% yield).
