実験手順

Et3N (28 μL), HOBT (15 mg) and WSC hydrochloride (19 mg) were added to a DMF (3 mL) solution of 4-(2-methyl-1,3-oxazol-5-yl)-3,5-dimethoxybenzoic acid (22 mg) and 6-(tetrazol-5-yl)spiro[chroman-2,4′-piperidin]-4-one hydrochloride (32 mg), and stirred overnight at room temperature. Water was added to the reaction liquid, the formed solid was taken out through filtration, and the solid was washed with water and ether. The solid was dried under reduced pressure to obtain the title compound. 1H-NMR (400 MHz, DMSO-d6) δ: 8.42 (1H, d, J=4.0 Hz), 8.23 (1H, dd, J=8.0, 4.0 Hz), 7.32 (1H, d, J=8.0 Hz), 7.08 (1H, s), 6.75 (2H, s), 4.32-4.18 (1H, m), 3.79 (6H, s), 3.64-3.20 (3H, m), 2.97 (2H, s), 2.41 (3H, s), 2.10-1.75 (4H, m). MS [M+H]+=531.
