3-Fluorobenzylamine → N-(3-fluorobenzyl)-2-[(pyridin-3-ylamino)sulfonyl]benzamide

Participants

Reaction Steps

The title compound was prepared according to procedures described above, using methyl 2-[(pyridin-3-ylamino)sulfonyl]benzoate and 3-fluorobenzylamine. The title compound was further purified by dissolving 25 g in EtOH (300 mL) and gently heating using water bath to 80° C. The resulting solids material were then slowly dissolved and more EtOH (50 mL) was added to completely dissolve all the solids. The solution left at room temperature to crystallize for 1 h. The resulting crystals were collected and dried under high vacuum for 16 h to afford the title compound as a crystalline solid (21 g, 84%). 1H NMR (400 MHz, DMSO-D6) δ 9.76 (s, 1H) 9.32 (t, 1H) 8.31 (d, 1H) 8.25 (d, 1H) 7.66-7.78 (m, 2H) 7.50-7.65 (m, 3H) 7.39 (q, 1H) 7.23-7.29 (m, 3H) 7.09 (t, 1H) 4.54 (d, 2H).
