Reaction Conditions

Reaction Steps

A mixture of 2-(3-acetamidophenyl)-4-bromo-6-morpholinopyrimidine (0.037 g), 2-methoxypyrimidin-5-ylboronic acid (0.019 g), tetrakis(triphenylphosphine)palladium(0) (3 mg), a saturated aqueous sodium bicarbonate solution (0.2 ml) and 1,2-dimethoxyethane (2 ml) was stirred and heated to 60° C. for 18 hours under an atmosphere of nitrogen. A second portion of each of 2-methoxypyrimidin-5-ylboronic acid (0.019 g), tetrakis(triphenylphosphine)palladium(0) (2 mg), a saturated aqueous sodium bicarbonate solution (0.2 ml) and 1,2-dimethoxyethane (1 ml) was added and the resultant mixture was heated to 60° C. for a further 18 hours. The resultant reaction mixture was evaporated and the residue was triturated under a 5:1 mixture (1 ml) of methylene chloride and methanol. The soluble material was purified by column chromatography on reversed-phase silica using an ‘Isolute SCX’ column (1 g; International Sorbent Technology Limited, Mid Glamorgan, UK) by initially washing the column with methanol (5 ml) followed by elution with a 5:3:2 mixture of methanol, methylene chloride and a 7M methanolic ammonia solution. The material so obtained was dried under vacuum. There was thus obtained the title compound as a solid (0.034 g); NMR Spectrum: (DMSOd6) 2.05 (s, 3H), 3.66-3.8 (m, 8H), 3.97 (s, 3H), 7.3-7.37 (m, 2H), 7.82 (d, 1H), 8.03-8.09 (m, 1H), 8.52 (s, 1H), 9.38 (s, 2H), 9.98 (s, 1H); Mass Spectrum: M+H+407.
