11-(2-Oxopyrrolidin-1-ylmethyl)-1,2,3,4,5,6,11,11a-octahydropyrido[2,1-b]quinazolin-6-one dihydrate

In the crystal structure of the title compound, C17H21N3O2·2H2O, water molecules are mutually O—H...O hydrogen bonded and form infinite chains propagating along the b axis. Neighboring chains are linked by the quinazoline molecules by means of O—H...O=C hydrogen bonds, forming a two–dimensional network
