To a stirred solution of N-cyclopropyl-4-methyl-3-{[4-(5-benzyloxypyridin-2-ylmethoxy)benzoyl]amino}benzamide (1.0 g, 1.97 mmol) in glacial acetic acid (10 mL) was added a solution of HBr (48% in acetic acid, 30 mL). After 6 hours at 25° C. the solution was diluted with ether (100 mL) and the resultant precipitate filtered off and dried to give the title compound as a pale yellow solid (610 mg, 62%); NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.68 (m, 2H), 2.25 (s, 3H), 2.84 (m, 1H), 5.36 (s, 2H), 7.18 (d, 2H), 7.31 (d, 1H), 7.63 (dd, 1H), 7.78-7.84 (m, 3H), 8.00 (d, 2H), 8.36 (m, 2H), 9.86 (s, 1H); Mass Spectrum: M+H+ 418.
