Equimolar amounts of 5-(5-cyclopropyl-1,2,4-oxadiazol-3-yl)-2,3-dihydrodiimidazo[1,5-a:1',2'-c]quinazoline (0.64 g) and L-tartaric acid (0.30 g) was stirred in dichloromethane (25 ml) until a clear solution was obtained. The solvent was removed by evaporation in vacuo and the residue was triturated with isopropyl alcohol. The crystalline precipitate was filtered off and recrystallized from ethanol yielding the title compound as pale crystals, m.p. 160°-163° C. (Compound 41).
