Embodiment
[0158] General experiment
[0159] Commercially available starting materials, reagents and dry solvents were used as provided.
[0160] Flash column chromatography was performed using Merck silica gel 60 (0.025mm-0.04mm). Column chromatography was also performed on the FlashMaster personal unit using isolute Flash silica columns or the Biotage SP1 purification system using Merck or Biotage flash silica cartridges.
[0161] Preparative TLC was performed on Analtech or Merck plates. Ion exchange chromatography uses acidic Isolute FlashSCX-II column, Isolute Si-carbonate column or basic isolute Flash NH 2 column carried out. Preparative HPLC uses a Phenomenex Luna column (5 μm, 250 x 21.2 mm, C18, Phenomenex, Torrance, USA) using a Gilson GX-281 liquid handler system in conjunction with a Gilson 322 HPLC pump (Gilson, Middleton, USA) from 10:90 to 100: 0 methanol:water (both modified with 0.1% formic acid) with a 15-minute gradient elution (Grad15mins20mls.m) at a flow rate o...

[0174] Example 2-isopropyl 6-(2-methoxy-4-(1-methyl-1H-tetrazol-5-yl)phenylamino)-2-(1-methyl- Synthesis of 1H-pyrazol-4-yl)-1H-pyrrolo[3,2-c]pyridine-1-carboxylate
[0175] Synthesis of 3-methoxy-N-methyl-4-nitrobenzamide
[0176]
[0177] HATU (0.501 g, 1.319 mmol) was added to a solution of 3-methoxy-4-nitrobenzoic acid (0.2 g, 1.014 mmol), DIPEA (0.265 mL, 1.522 mmol) and 2M methylamine in THF (1.0 mL, 2.029 mmol) in THF (2.7 mL). The reaction mixture was stirred overnight at rt. It was then concentrated under reduced pressure and purified by Biotage column chromatography (DCM / EtOAc 80 / 20 to 60 / 40; 25g column) and subsequently (cyclohexane / EtOAc 50 / 50 to 40 / 60, 25g column) to give The title compound as a white solid (166 mg, 78%). 1 H NMR (500MHz, CDCl 3 ): δ3.07(d,J=4.9Hz,3H),4.04(s,3H),6.27(app s,1H),7.28(dd,J=8.3,1.6Hz,1H),7.64(d,J = 1.6Hz, 1H), 7.88 (d, J = 8.3Hz, 1H); LC (method B)-MS (ESI, m / z) t R 2.04min,211[(M+H + ), 100%].
