Procedure

To a stirred solution of (vi) (15 g, unpurified from the previous step) in DMF (300 mL) was added DIPEA (27.7 mL, 0.16 mol), HATU (23.9 g, 0.06 mol) and methylamine (2.0M solution in THF, 60 mL, 0.12 mol). The reaction mixture was stirred for 2 h at RT and then poured onto the ice. The precipitate was then separated by filtration and the solid obtained was dissolved in DCM (300 mL), dried (Na2SO4) and the volatiles removed in vacuo to give (vii) (16.5 g with purity 86.5% by HPLC analysis), which was used unpurified in subsequent steps. ESI-MS m/z calculated for [M+H]+: 371.1. found: 371.0. 1H NMR (400 MHz, CDCl3) δ 8.23 (s, 1H), 7.74 (s, 1H), 7.62-7.45 (m, 4H), 5.91 (brs, 1H), 3.09-2.97 (m, 3H), 2.40-2.28 (m, 1H), 1.04-0.95 (m, 2H), 0.73-0.65 (m, 2H).
