Procedure
As in the synthesis of N-(2-azidoethyl)tetradecanamide, 3,5-difluorobenzoyl chloride (0.219 g, 1.24 mmol) was reacted with 2-azidoethanamine (0.107 g, 1.24 mmol) and triethylamine (0.251 g, 2.48 mmol) in dichloromethane (5 mL) to give N-(2-azidoethyl)-3,5-difluorobenzamide (0.280 g, 59% yield). 1H NMR (300 MHz, CDCl3) δ 7.32 (s, 2H), 7.29 (s, 1H), 6.91 (t, J=2.4 Hz, 1H), 3.58 (q, J=5.7, 5.1 Hz, 2H), 3.51 (t, J=4.8 Hz, 2H) ppm; 13C NMR (75 MHz, CDCl3) δ 165.9, 164.7, 161.5, 161.4, 137.6, 110.7, 106.9, 50.7, 39.9 ppm; HRMS (ESI) calcd for C9H8F2N4O2S (M+) 226.0666. found 226.0662.
