3-amino-1-piperidin-1-ylpropan-1-one;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 150 mg (0.57 mmol) of 4-allylamino-2-chloro-6-nitroquinazoline was dissolved in 10 ml of acetonitrile, and then 220 mg (1.14 mmol) of 2-piperidinocarbonylethylamine hydrochloride and 0.40 ml (2.85 mmol) of triethylamine were added thereto, followed by heating under reflux overnight. To the reaction solution was added water, followed by extraction with ethyl acetate, washing with brine and drying over anhydrous sodium sulfate. After the solvent was distilled off, the residue was purified by a silica gel column to give 191 mg (87.7%) of the title compound. by heating under reflux overnight followed by extraction with ethyl acetate washing with brine drying over anhydrous sodium sulfate After the solvent was distilled off the residue was purified by a silica gel column
