실험 절차

The (cyclopropylmethyl){[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amine used to prepare 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(5-{[(1-methylethyl)amino]methyl}-3-pyridinyl)-1H-indole-7-carboxamide was prepared as follows: isopropylamine (0.011 mL, 0.129 mmol) was added to a solution of 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinecarbaldehyde (30 mg, 0.129 mmol) in MeOH (1 mL) in a 2-dram vial. NaCNBH3 (16 mg, 0.258 mmol) was then added, the vial was capped and the reaction was stirred at room temperature for 24 h. The reaction mixture was filtered through a 2 g SCX cartridge (pre-equilibrated with 3 mL MeOH), eluting in sequence with MeOH (6 mL) and a 2 M solution of NH3/MeOH (9 mL). The NH3/MeOH fraction was concentrated under a stream of nitrogen to give 22 mg of crude (1-methylethyl){[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3-pyridinyl]methyl}amine.
