Reaction Steps
To a solution of oxazole (0.5 ml, 7.2 mmoles) in 10 ml of THF at −78° C. is added BuLi (5.23 ml, 8.0 mmoles, 1.6 M solution in hexane). After 30 min, ZnCl2 (3.0 g, 21.7 mmoles) and then a solution of 4-{(2,2-Dimethyl-propyl)-[4-iodo-benzyl]-amino}-pyrimidine-2-carbonitrile (2.9 g, 7.2 mmoles) in 10 ml of THF are added. The reaction mixture is warmed to 0° C. for 1 h. The reaction mixture is added to Pd(PPh3)4 (0.9 g, 0.8 mmoles) and heated to reflux. Water is added and is filtered through a pad of Celite which is washed with AcOEt. The organic layer is extracted with AcOEt, washed with brine, dried over magnesium sulfate and concentrated. The crude product is purified by silica gel column chromatography to give 104 mg of desired 4-[(2,2-dimethyl-propyl)-(4-oxazol-2-yl-benzyl)-amino]-pyrimidine-2-carbonitrile in 16% yield.
