Product Name:2-Morpholinoethyl isocyanide
CAS Number:78375-48-1
Molecular formula:C7H12N2O
Molecular Weight:140.19

2-Morpholinoethyl isocyanide is prepared by the reaction of 2-morpholinoethylamine with Formic Acid in boiling toluene with a water separator, to yield the formamide which is treated either with Phosgene and Triethylamine in CH2Cl2 or with Phosphorus Oxychloride and Diisopropylamine. The use of diisopropylamine as base is favored as yields are improved, typically to 68%. Trichloroacetic Anhydride has also been used as an alternative for COCl2, giving a yield of 74%.
