実験手順

To a mixture of tert-butyl 5-(aminomethyl)-4,6-dimethylpyridin-2-ylcarbamate (80.0 mg, 0.318 mmol) in DCM (3 ml) were added HOAt (87.0 mg, 0.637 mmol), collidine (0.127 ml, 0.955 mmol), 1-(4-methoxybenzyl)-1H-pyrazole-4-carboxylic acid (73.9 mg, 0.318 mmol) and HATU (81.0 mg, 0.212 mmol). After stirring for 2 h at rt, all volatiles were removed in vacuo. The crude intermediate was purified by column chromatography (CombiFlash Companion, 12 g SiO2, TBME to TBME+10% MeOH), dissolved in DCM (3 ml) and TFA (1 ml), kept for 14 h at rt, and concentrated. Purification by column chromatography (CombiFlash Rf, 13 g RediSep Rf C18, MeCN:water 5:95+0.1% TFA to MeCN) afforded the title compound as. 1H-NMR (DMSO-d6, 400 MHz): 2.37 (s, 3H), 3.73 (s, 3H), 4.27 (d, 2H), 5.24 (s, 1H), 6.64 (s, 1H), 6.91 (d, 2H), 7.23 (d, 2H), 7.70 (br, s, 2H), 7.84 (s, 1H), 8.14-8.19 (m, 2H), 13.59 (s, 1H). LCMS RtK=0.71 min, [M+H]+=366.4.
