Reaction Steps

To a mixture of N-{[6-(4,4-difluorocyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl}-1-methoxy-2-methylpropan-2-amine (110 mg), 1H-benzotriazole-1-methanol (86 mg), and DCE was added NaBH(OAc)3 (182 mg), followed by stirring at room temperature for 4 hours. To the reaction mixture was added water, followed by extraction with EtOAc. The organic layer was washed with brine, dried over Na2SO4, and then concentrated under reduced pressure. The residue was purified by basic silica gel column (hexane/EtOAc) to obtain N-{[6-(4,4-difluorocyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl}-1-methoxy-N,2-dimethylpropan-2-amine (93 mg). This product was dissolved in MeOH, and fumaric acid (27 mg) was added thereto, followed by concentration under reduced pressure to obtain N-{[6-(4,4-difluorocyclohexyl)-2-methylthieno[2,3-d]pyrimidin-4-yl]methyl}-1-methoxy-N,2-dimethylpropan-2-aminefumarate (117 mg).
