실험 절차

A mixture of 5-(4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulen-2-yl)-1-isopropyl-1H-[1,2,4]triazole-3-carbaldehyde (85 mg, 0.26 mmol), acetic acid (catalytic, 2 drops), 4 Å molecular sieves and dimethylamine hydrochloride (24 mg, 0.29 mmol) in THF (5 mL) was stirred at RT for 10 min before the addition of sodium triacetoxyborohydride (66 mg, 0.31 mmol). After stirring at RT for a further 18 h the reaction mixture was diluted with DCM, the organic layer washed with saturated aqueous sodium bicarbonate followed by water and then brine, then dried (Na2SO4), filtered and concentrated in vacuo. The resultant residue was subjected to RPHPLC (C18 column, gradient 5 to 98% methanol in water+0.1% HCO2H) to give 318 as a white solid (13 mg, 14%). LCMS: RT=3.18 min, [M+H]+ 353. 1H NMR 400 MHz (DMSO-d6) δ: 8.45 (1H, dd, J=8.02, 1.76 Hz), 7.97 (1H, s), 7.39-7.32 (1H, m), 7.19-7.19 (1H, m), 7.09 (1H, dd, J=8.15, 1.25 Hz), 5.89 (1H, m), 4.54 (4H, d, J=2.46 Hz), 3.47 (2H, s), 2.24 (6H, s), 1.51 (6H, d, J=6.59 Hz)
