With sodium carbonate;tetrakis(triphenylphosphine) palladium(0); In 1,2-dimethoxyethane; water; at 100℃; for 12h; | A mixture of Intermediate 3 (602 mg), 2-methoxypyrimidme-5-boronic acid(Frontier, 1.5 eq, 706 mg), and tetrakis(triphenylphosphine)palladium (0) (352 mg) was heated in DME / 2N sodium carbonate (aq, 2:1, 20 ml) at 100 ° for 12 h. Aqueous workup between water and EtOAc gave a brown solid that purified by SPE (Si, 20 g) by elution with DCM (4x10 ml) then EtOAc (4x10 ml), to give a solid that was triturated with DCM / petrol, and filtered to give a light brown solid (660 mg).1H NMR delta 8.85 (2H, s), 7.8 (IH, s), 7.6 (>3H, m), 6.88 (IH, d, J 8.85Hz), 6.3 (2H, s), 3.93 (3H, s); LC-MS rt 2.39 m/z 226 ES-. |

The intermediates described below in Table 1 were prepared as follows: To 200 mg (1.130 mmol) of the appropriate ketone dissolved in 10 ml of 10% AcOH/MeOH was added 1.6 mmol (1.5 equiv) of the appropriate aniline, and then 0.14 ml (1.130 mmol) of 8 M BH3 py solution. The reaction mixture was stirred at rt for 2 hr and then the solvents were evaporated. To the residue was added 5 ml of 1 N HCl and stirred vigorously for about 5 min, and then 20 ml of DCM was added. Solid Na2CO3 was used to adjust the pH to 9. The organic layer was separated, and the aqueous layer was extracted twice with DCM. The combined organic layers were washed with brine and dried over MgSO4. It was concentrated and purified by ISCO eluting with 5 -35% EtO Ac/hex. Yields on these reactions were all over 80%, except with the cyano anilines where the yields were about 22%. |
