Reaction Steps

To homopiperonylamine hydrochloride (2.14 g, 10.6 mmol) (a compound of formula (Y7)) in CH2Cl2 (20 mL) in an ice bath was added triethylamine (3.1 mL, 21 mmol) and chloroacetyl chloride (0.85 mL, 10 mmol) (a compound of formula (Y6)). After warming to ambient temperature and stirring for 16 hours, the reaction was partitioned with 1 N HCl. The organic layer was separated, washed with aqueous bicarbonate, dried (Na2SO4), and the solvent was removed in vacuo to give 1.8 g of 2-chloro-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide, a compound of formula (Y8).
