Water ethanol → HCID 57986808, compound

Participants

Reaction Steps

4-[4-(4-Tetrazol-1-yl-phenoxymethyl)-thiazol-2-yl]-piperidine-1-carbonitrile (1.07 g, 2.92 mmol) was dissolved in 4 N HCl in ethanol/water (1:1). The solution was refluxed for 1 hour, cooled and the solid precipitate was filtered off. The filtrate was neutralized by the addition of excess sodium carbonate. The excess sodium carbonate was filtered off and the filtrate was diluted with EtOAc. The solution was washed with water, separated, dried (Na2SO4), filtered and concentrated. The residual oil was chromatographed on silica gel (1:1 Hexanes/EtOAc) to afford the desired compound. 1H NMR (CDCl3): δ 8.92 (1H, s), 7.60 (2H, d), 7.23 (1H, s), 7.167 (2H, d), 5.21 (2H, s), 4.25 (2H, m), 4.15 (2H, m), 3.22 (1H, m), 2.90 (2H, m), 2.18 (2H, m).
