Procedure

To 2-chloro-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide (0.45 g, 1.9 mmol) in ethanol (10 mL) was added 3-aminopropanol (0.72 mL, 9.4 mmol) (a compound of formula (Y9)). After heating the reaction in an oil bath at 60° C. for 1 day, the reaction was partitioned with ethyl acetate and water. The organic layer was separated, washed with brine, dried (Na2SO4), and the solvent was removed in vacuo to give 0.44 g of 2-[(3-hydroxypropyl)amino]-N-[2-(1,3-benzodioxol-5-yl)ethyl]acetamide, a compound of formula (Y10).
