4-Bromobenzoic acid → HCID 68407394, compound

Participants

Reaction Steps

4-(4,6-Dimethoxy-1,3,5-triazinyl-2-yl)-4-methylmorpholinium chloride (Method 18; 5.4 g, 19.4 mmol) was added to a solution of 4-bromobenzoic acid (3.5 g, 17.4 mmol) and 1-(N-t-butoxycarbonylamino)-2-aminobenzene (Method 17; 4.3 g, 20.9 mmol) in DMF (100 ml) and stirred at ambient temperature for 20 hours. The reaction mixture was partitioned between water and ethyl acetate. The organics were washed with a saturated aqueous solution of sodium hydrogen carbonate, water, 1M aqueous hydrochloric acid, water and brine, before being dried over magnesium sulfate. The organics were then evaporated to give the title compound (7.1 g, quantitative), which was used without further purification. NMR Spectrum: (DMSO-d6): 1.45 (s, 9H), 7.18 (m, 2H), 7.54 (m, 2H), 7.76 (d, 2H), 7.90 (d, 2H), 8.63 (s, 1H), 9.86 (s, 1H); Mass Spectrum: (M+H+-Boc) 291.
