Reaction Steps

To a suspension of 2-(2-chloro-6-methyl-benzylamino)-thiazol-4-one (example 18a, 40.8 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 30 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-6-methyl-benzylamino)-5-(4-ethoxy-2-methylamino-quinazolin-6-ylmethylene)-thiazol-4-one as a light brown solid: 45.9 mg (61.3%), MS: m/e 468 (MH+).
