Procedure
Sodium methylate (0.11 g; 0.002 mole) is added to a solution of methyl 2-cyanonicotinate (3.24 g; 0.02 mole) and 2-(3-chlorophenyl)-4-(hydroxymethyl)thiazole (4.96 g; 0.022 mole) in toluene (100 cc). The methanol/toluene azeotrope is distilled off and the toluene is then evaporated off. The residue is treated with water. The precipitate formed is filtered off, washed with water and then dried. Compound 2 (1.8 g; 25% m.p. 130° C.) is obtained.
