실험 절차

To 1-(4-(1-(4-(trifluoromethoxy)phenyl)-1H-1,2,4-triazol-3-yl)phenyl)propan-2-amine (CB58) (0.60 g, 1.7 mmol) in methanol (10 mL) was added (2S,3S)-2,3-dihydroxysuccinic acid (0.25 g, 1.7 mmol). The resultant solid was filtered and air dried overnight: mp 182-185° C. The solid was redissolved in methanol (10 mL) and heated to reflux (˜65° C.). The solution was cooled to room temperature and let stand overnight. The white solid that formed was filtered and air-dried to give the title compound as a white solid (0.40 g, 46%): mp 191-194° C.; 1H NMR (400 MHz, CDOD3) d 9.16 (s, 1H), 8.15 (d, J=8.2 Hz, 2H), 8.02 (d, J=9.1 Hz, 2H), 7.50 (dd, J=9.2, 1.0 Hz, 2H), 7.41 (d, J=8.2 Hz, 2H), 4.40 (s, 2H), 3.59 (dt, J=8.1, 6.2 Hz, 1H), 3.07 (dd, J=13.6, 6.1 Hz, 1H), 2.88 (dd, J=13.6, 8.3 Hz, 1H), 1.29 (d, J=6.5 Hz, 3H) (OH and NH2 not observed).
