Dichloromethane → Ethyl 2-((dimethylamino)methyl)thiazole-4-carboxylate

Participants

Reaction Steps

2-Chloromethyl-thiazole-4-carboxylic acid ethyl ester (500 mg, 2.431 mmol) and potassium carbonate (504 mg, 3.65 mmol) were dissolved in dry DMF. Dimethylamine hydrochloride (218 mg, 2.67 mmol) in dry DMF was added slowly to the reaction mixture and stirred at RT over three nights. DCM was added and the mixture was washed with concentrated NaHCO3 and water. Organic phase was evaporated to dryness and the product was purified by Flash-chromatography. Yield 34.2%. 1H-NMR (400 MHz; CDCl3): δ 1.41 (t, 3H), 2.49 (s, 6H), 3.99 (s, 2H) 4.43 (q, 2H), 8.20 (s, 1H).
