Procedure
Isobutylamine (7.3 g, 0.1 mol) was dissolved in 20 ml of diethyl ether and cooled to less than 5° C. Chloroethyl isocyanate (10.5 g, 0.1 mol) dissolved in 15 ml of ether was added maintaining a temperature between 0° and 5° C. with vigorous stirring. Stirring continued an additional 2 hrs. the mixture was cooled to -5° C., and the product (4.1 g, 46%) was filtered and dried in vacuo for 18 hrs. over KOH, MP 79.5° C. (decomposes). IR analysis showed peaks at 1630/cm (C=O) and 1585/cm (N--C=O). NMR: Doublet at 0.9 ppm (J=6.4 Hz), multiplet (1H) at 2.1 ppm, quartet (2H) at 2.9 ppm (J=6.4 Hz), multiplet (4H) at 3.5 ppm.
