Triethylamine hydrochloride → HCID 23131657, compound

Participants

Reaction Steps

Four grams (15.5 mmol) of N-(naphthalen-1-yl)-2,2,2-trifluoroacetimidoyl chloride obtained in Example 13, 1.84 g (27.9 mmol) of sodium azide, 1.08 g (7.76 mmol) of triethylamine hydrochloride, and 40 ml of toluene were introduced into a 100 ml flask and reacted at 80° C. for 14 hours. After the reaction, the reaction solution was cooled to room temperature and washed with water (30 ml×2). The organic phase was dried over anhydrous magnesium sulfate for 1 hour, filtered, and then subjected to solvent removal by evaporation. The crude product thus obtained was precipitated for 1 hour in 18 ml of n-hexane while being cooled using an ice bath, followed by filtration and drying, thereby giving 3.86 g of 1-(naphthalen-1-yl)-5-(trifluoromethyl)-1H-tetrazole as a white powder (yield: 94.1%).
