Participants

Reaction Steps

A solution of methyl 4-({[(2-chloro-5-hydroxyphenyl)carbonyl]amino}methyl)benzoate (100 mg, 0.31 mmol) in THF (5 ml) was treated with triphenylphosphine (1.2 eq, 98 mg, 0.37 mmol), (2-methyl-3-pyridinyl)methanol (38 mg, 0.31 mmol) and diisopropylazodicarboxylate (1.2 eq, 110 ul, 0.56 mmol) and stirred at room temperature for 4 hours. Mixture diluted with methanol and purified by SCX cartridge eluting with methanol first then 2M ammonia in methanol. Basic fractions combined and evaporated to give the title compound as an off-white solid. MS (ES+) m/z 425 [M+H]+ (C23H2135ClN2O4). 1H-NMR (400 MHz, d6-DMSO) δ 3.85 (3H, s), 4.51 (2H, d, J 6), 5.18 (2H, s), 7.10-7.96 (9H, m), 8.42 (1H, dd, J 1.6, J 4.8), 9.07 (1H, t, J 6).
