After one hr, methyl 2-bromopropionate (2.51 ml) was added and stirring was continued overnight. The reaction mixture was diluted with water, extracted with ethyl acetate, dried over anhydrous sodium sulfate, concentrated, and the residue was flash chromatographed (ethyl acetate, then 5% triethylamine/ethyl acetate) to yield 4.05 g (86.7%) of methyl α-[(9-amino-1,2,3,4-tetrahydroacridin-8-yl)oxy]propionate hydrate.
