Procedure

Using the same conditions as in Example 7, 5.1 parts of 2,2,7,7 -tetramethyl-1,4-diazaheptan-5-one, 30 parts of isobutylchloroformate and 150 parts of anhydrous toluene afforded 4-isobutoxycarbonyl-2,2,7,7-tetramethyl-1,4-diazaheptan-5-one of boiling point 134°C at 0.8mm pressure. The hydrochloric acid salt of this material showed a melting point of 179° -181°C and gave the following elemental analysis by weight:
