Ammonium Chloride → HCID 178478060, compound

Participants

Reaction Steps

To a solution 4-(4-chlorobenzyl)-2-(pyridin-4-yl)thiazole-5-carbonitrile (167 mg, 0.536 mmol) in DMF (3.5 mL) was added sodium azide (104 mg, 1.61 mmol) and ammonium chloride (86 mg, 1.61 mmol) and the resulting mixture was heated at 100 degrees overnight. The reaction was cooled and taken up in ethyl acetate and water. The aqueous layer was concentrated in vacuo, and the residue was purified by silica gel chromatography (MeOH/DCM=0/100→10/90) to give 9 mg (5% yield) of the title compound. LC/MS (FA) ES+ 355, 357. 1H NMR (400 MHz, DMSO-d6) δ: 8.74-8.73 (m, 2H), 7.93-7.92 (m, 2H), 7.38-7.32 (m, 4H), 4.62 (s, 2H).
