Procedure

Isobutyl chloroformate (226 μL, 1.73 mmol) was added to a solution of N-Boc sarcosine (1.73 mmol) and N-methylmorpholine (192 μL, 1.73 mmol) in THF. After two minutes, piperonylamine (216 mL, 1.73 mmol) was added and the mixture allowed to warm to room temperature. After thirty minutes, the reaction mixture was passed through a bed of Celite and all volatiles were removed under reduced pressure to yield N-Boc sarcosine piperonyl amide (531 mg, 95%) as a white solid. 1H NMR: (CDCl3) δ2.41 (s,3), 3.28 (s,2), 4.39 (d,2), 5.95 (s,2), 6.80 (m,3), 7.43 (bs,1), 9.04 (bs,1).
