To a N-(1-cyclohexen-1-yl)morpholine 3 (1.84 g, 0.011 mol, 80% from cyclohexanone and morpholine) and TEA (1.53 mL, 0.011 mol) in CHCl3(13.0 mL) was added acid chloride 4 (2.02 g, 0.01 mol) in CHCl3 (9.0 mL) at 35 C during 2.5 h. After12 h the red solution was refluxed with 32% HCl (5.0 mL) for 5 h. The organic layer was washed anddistilled to afford 5 (70%).【Chem Ber.,1962, 95, 2493】

Being Jewish, he immigrated to the US due to rising antisemitism. He earned his Ph.D. at Wisconsin in 1945 and later became an assistant professor at Harvard. Since he was not awarded tenure in 1953, Stork moved to Columbia University where he has taught ever since.2. Singerman, G.; Danishefsky, S. Tetrahedron Lett. 1964, 5, 2249.3.
