3-methylbutyl carbamate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: The procedure described in Example 4 is followed, but the n-pentanol and n-pentyl carbamate are replaced respectively by isoamyl alcohol and isoamyl carbamate, and diazabicyclo-[4,3,0]-nonene is used as the catalyst. After completion of the reaction, analysis by gas chromatography shows that 66.9% of isoamyl carbamate have been converted and 120.3 parts of diisoamyl carbonate (89% of theory, based on converted isoamyl carbamate), of boiling point 106°-108° C./18 mbar, have been formed. After completion of the reaction, analysis by gas chromatography
