Procedure

[2-(2-Methoxy-phenyl)-7-methyl-quinazolin-4-yl]-(5-methyl-[1,3,4]oxadiazol-2-ylmethyl)-amine 4-Chloro-2-(2-methoxy-phenyl)-7-methyl-quinazoline (400 mg, 1.48 mmol) was dissolved in 10 ml dry DMF followed by the addition of C-(5-Methyl-[1,3,4]oxadiazol-2-yl)-methylamine oxalate (234 mg, 1.48 mmol) then triethylamine (413 μL, 2.96 mmol). After 6 hours the reaction was complete, partitioned between EtOAc and water. The organic phase was separated, dried over MgSO4, filtered and concentrated to an oil. Purified by flash chromatography 60% EtOAc/40% hexanes to afford the desired product a white solid. Recovered 290 mg 56% yield. LC/MS (10-99%) M/Z 348.4, retention time 2.17 minutes.
