Safety of 4-(1,2,4-Triazol-1-yl)aniline

A mixture of formamidine from Step 3 (594 mg) and 4-triazolyl-aniline(279 mg, 1 eq) in AcOH (6 ml) was heated to 125 for 2 h. On cooling and dilution with water (20 ml), a yellow precipitate was isolated by filtration, slurried with IN NaOH and washed with water. After drying, this material was triturated with MeOH / water/ acetone ~ 10:5:5 to give, after filtration and drying, a pale cream solid (510mg, 64%).1H NMR delta 10.1 (IH, br s), 9.27(1H, s), 8.8 (IH, s), 8.58 (IH, s), 8.24(1H, s), 8.18 (IH, d, J 8.85Hz), 8.03 (2H, d, J8.85Hz), 7.84 (4H, m), 7.68 (IH5 d, J9.5Hz), 7.35 (IH, t, J 8.85Hz), 4.26 (2H, m), 3.72 (2H, m), 3.35 (3H, obscured by H2O); LC-MS rt 2.4 m/z 457 ES+.

General procedure: An aqueous solution of cesium carbonate (130 mg, 0.4 mmol) in water (300 ul) was dispensed into each well containing a pre-mixed solution of 4-chloro-N-(4-methoxyphenyl)pyridin-2-amine (58.8 mg, 0.2mmol), respective aniline (0.26 mmol), xantphos (13.9 mg, 0.024mmol) and palladium (II) acetate (3.6 mg, 0.016 mmol) in DMA (1.25 ml). The resultant plate was placed on a pre-heated SOPHAS base plate set at 150 oC and shaken for 1 hour. The plate was cooled to room temperature and MP-TMT resin (90 mg) added to each well prior to shaking overnight at room temperature. The following day each well was transferred to a 48 well filter plate, washing through with an extra aliquot of DMA (200 ul) before a final centrifuge. The crude filtrates were then purified by preparative HPLC (Waters XBridge Prep C18 OBD column, 5mu silica, 19 mm diameter, 100 mm length), using decreasingly polar mixtures of water (containing 1% NH3) and MeCN as eluents.
