실험 절차

At room temperature, a soln. of 4-[(2,2-Dimethyl-propyl)-(4-iodo-benzyl)-amino]-pyrimidine-2-carbonitrile (2 g, 4.9 mmoles) and ethynyl-trimethyl-silane (3.47 ml, 24.7 mmoles) in 20 ml of DMF is treated with triethylamine (2.6 ml, 14.8 mmoles), CuI (93 mg, 0.5 mmoles) and (Ph3P)2PdCl2 (0.2 g, 0.2 mmoles). The mixture is stirred at rt for overnght. Water is added and the organic layer is extracted with AcOEt, washed with brine, dried over magnesum sulfate and concentrated. The crude product is purified by silica gel column chromatography to give 6.1 g of desired 4-[(2,2-dimethyl-propyl)-(4-trimethylsilanylethynyl-benzyl)-amino]-pyrimidine-2-carbonitrile in 82% yield. Rf=0.52 (Hexane:AcOEt=1:1)
