YieldReaction ConditionsOperation in experiment
52% Stage 2: 2-(Pyridin-3-yl)-1,3-thiazole-4-carboxylic acid 5.90 g (19.0 mmol) of ethyl 2-(pyridin-3-yl)-1,3-thiazole-4-carboxylate hydrobromide were dissolved in 2 ml of water, and 3.30 g (38.0 mmol) of 45% aqueous sodium hydroxide solution were added. After evolution of heat had ended, the mixture was left to react for two hours at room temperature. After cooling with ice-water, the precipitated solid was removed and, while cooling with ice, the reaction solution was adjusted to pH 4 with dilute hydrochloric acid. The precipitated solid was filtered off, washed with water and acetone, and dried under high vacuum. Yield: 2.03 g (52% of theory); HPLC-MS: logP (HCOOH)=0.35; mass (m/z): 207.0 (M+H)+; 1H NMR (d6-DMSO): 7.55 (m, 1H), 8.35 (m, 1H), 8.50 (s, 1H), 8.70 (m, 1H) 9.15 ppm (m, 1H).
