Reaction Steps

A suspension containing 2-bromo-5-methyl-1,3,4-thiadiazole (Modarai, B., et al. J. Heterocyclic Chem. (1974) 11, 343-5) (100 mg, 0.56 mmol), 4-piperidine ethanol (87 mg, 0.67 mmol) and potassium carbonate (77 mg, 0.56 mmol) was heated overnight at 120° C. The reaction was cooled and the mixture partitioned between water (10 ml) and ethyl acetate (30 ml), then the organic layer was washed with brine, dried (Na2SO4) and concentrated. Chromatography of the residue on silica gel (8 g; eluent 2.5% methanol/DCM) gave 1-(5-methyl-1,3,4-thiadiazol-2-yl)-4-(2-hydroxyethyl)piperidine (41 mg, 32%), 1H nmr; 1.33 (m, 2H), 1.54 (q, 2H), 1.7 (m, 1H), 1.79 (m, 2H), 2.54 (s, 3H), 3.08 (m, 2H), 3.71 (t, 2H), 3.88 (m, 2).
