Reaction Steps

A solution of 4-(5-methyl-4-(p-tolyloxymethyl)oxazol-2-yl)benzoic acid (460 mg, 1.42 mmol, 1.00 equiv), EDCI (320 mg, 1.68 mmol, 1.18 equiv), HOBT (240 mg, 1.78 mmol, 1.25 equiv), pyridin-3-ylmethanamine (180 mg, 1.67 mmol, 1.17 equiv) and triethylamine (440 mg, 4.36 mmol, 3.06 equiv) in N,N-dimethylformamide (6 mL) was stirred overnight at room temperature. The resulting solution was diluted with 20 mL of ice/water. The solid was collected by filtration and washed with 3×10 mL of hexane. The crude product was purified on a silica gel column eluted with chloroform/methanol (50:1-20:1) to give 0.33 g (56%) of 4-(5-methyl-4-(p-tolyloxymethyl)oxazol-2-yl)-N-(pyridin-3-ylmethyl)benzamide as a gray solid. LC-MS: (ES, m/z): 414 [M+H]+. 1HNMR (400 MHz, DMSO-d6, ppm) δ 9.16 (s, 2H), 8.56 (s, 1H), 8.46 (s, 1H), 8.00-7.95 (m, 3H), 7.75 (d, 1H), 7.34 (m, 1H), 6.86-6.81 (m, 2H), 6.68 (d, 1H), 4.50 (d, 2H), 3.78 (s, 2H), 2.50 (s, 3H), 2.14 (s, 3H).
