Reaction Steps

To a suspension of 2-(2-chloro-benzylamino)-thiazol-4-one (example 13a, 38.5. mg, 0.16 mmole), and 4-ethoxy-2-methylamino-quinazoline-6-carbaldehyde (example 12f, 45.5 mg, 0.20 mmole) in 2 mL of toluene in a microwave tube were added benzoic acid (2.0 mg, 0.016 mmole) and piperidine (1.5 mg, 0.02 mmole). The reaction mixture was heated to 150° C. with microwave for 45 min. The reaction mixture was then cooled to r.t. and the solid was filtered off, washed with toluene, MeOH and ether to give 2-(2-chloro-benzylamino)-5-(4-ethoxy-2-methylamino-quinazolin-6-ylmethylene)-thiazol-4-one as a brown solid: 43.2 mg (59.5%), MS: m/e 454 (MH+).
