Participants

Reaction Steps

Tert-butylethylketone (5 g) was mixed with tert-butylcarbazate (6.4 g, 1.1 eq.) in 30 mL of methanol with 3 drops of acetic acid at room temperature. A solid formed within one hour; more methanol was added, and the mixture was stirred at room temperature for three days to produce N′-(1-ethyl-2,2-dimethyl-propylidene)-hydrazinecarboxylic acid tert-butyl ester. 1H NMR (CDCl3, 500 MHz) δ (ppm): 7.5 (br, 1H), 2.23 (q, 2H)), 1.51 (s, 9H), 1.15 (s, 9H), 1.1 (t, 3H).
