Participants

Reaction Steps

A mixture of 5-(methylamino)-2-pyridinecarbaldehyde and 6-[bis(methyloxy)methyl]-N-methyl-3-pyridinamine (D85) (0.622 g), 1,1-dimethylethyl (2S)-2-methyl-1-piperazinecarboxylate (0.910 g, 4.552 mmol) and triethylamine (0.418 g, 4.139 mmol) in 1,2-DCE (40 mL) was stirred at room temperature overnight. Sodium tri(acetoxy)borohydride (1.14 g, 5.38 mmol) was added and the reaction stirred at room temperature overnight. The reaction mixture was diluted with DCM and washed with saturated aq. NaHCO3 solution and water. The organic layer was dried and concentrated to give the crude product which was purified by column chromatography. Elution with 0-100% EtOAc/petroleum ether gave the title compound as a yellow/brown oil (0.542 g). δH (CDCl3, 400 MHz) 7.96 (1H, d), 7.23 (1H, d), 6.88 (1H, dd), 4.17 (1H, br.s), 3.80 (2H, d), 3.58 (1H, d), 3.45 (1H, d), 3.12 (1H, td), 2.86 (3H, s), 2.76 (1H, m), 2.58 (1H, m), 2.18 (1H, dd), 2.07 (1H, m), 1.45 (9H, s), 1.23 (3H, d). MS (ES): MH= 321.4
