Methyl chloroacetate → Methyl 2-((5-amino-4-(4-cyclopropylnaphthalen-1-yl)-4H-1,2,4-triazol-3-yl)thio)acetate

Participants

Reaction Steps

Methyl 2-chloroacetate (0.73 mL, 8.3 mmol) was added dropwise over 5 mins to a suspension of 5-amino-4-(1-cyclopropylnaphthalen-4-yl)-4H-1,2,4-triazole-3-thiol (2.24 g, 7.9 mmol) and potassium carbonate (1.21 g, 8.7 mmol) in DMF (40 mL) at room temperature. The reaction was stirred at room temperature for 24 h and slowly poured into a stirred ice-cold water solution. The tan precipitate was collected by vacuum filtration and dried under high vacuum at 50° C. for 16 h in the presence of P2O5 to yield methyl 2-(5-amino-4-(1-cyclopropylnaphthalen-4-yl)-4H-1,2,4-triazol-3-ylthio)acetate
