Procedure
To a solution of acid 402a (2.61 g; 8.36 mmol; 1 eq), 1,2-phenylenediamine (903 mg; 8.36 mmol; 1 eq) and BOP (3.70 g; 8.36 mmol; 1 eq) in dry DMF (20 ml) was added Et3N (4.64 ml; 33.4 mmol; 4 eq). After stirring overnight most of the DMF was removed under reduced pressure and chromatographed (Hex:EtAcO: 1:2/EtAcO). The crystal 402 was obtained in 70% (2.35 g). 1H-NMR (300.07 MHz; DMSO-d6) δ (ppm): 9.65 (s, 1H), 7.97 (d, J=7.9, 2H), 7.53 (d, J=7.9, 2H), 7.22 (d, J=7.5, 1H), 7.03 (dd, J=7.0, 7.5, 1H), 6.83 (d, J=7.9, 1H), 6.77 (d, J=8.8, 2H), 6.65 (dd, J=7.5, 7.0, 1H), 6.57 (d, J=8.8, 2H), 4.93 (bs, 2H), 4.36 (d, J=5.7, 2H), 3.75 (m, 4H), 2.93 (m, 4H). LRMS: calc 402.49. found: 403.4.
