Procedure

Under nitrogen, a solution of 18.9 g (100 mmol) of N-Boc glycine hydrazide (from step 2 of Example 3) in 100 mL of methanol is treated with 14.3 g (100 mmol) of ethyl iminocaproate [P. Reynaud and R. C. Moreau, Bull. Soc. Chim. France, 2997 (1964)]. The reaction is stirred at reflux overnight and concentrated in vacuo. Purification by silica gel chromatography (Waters Prep-500A) gives 5-pentyl-3-tertbutoxycarbonylaminomethyl-1H-1,2,4-triazole.
