Procedure
Methane sulfonyl chloride (40 μl, 0.49 mmol) was added to a mixture of TEA (95 μl, 0.67 mmol) and 1-[5-(3-chlorophenyl)-1,2,4-oxadiazol-3-yl]ethanol (100 mg, 0.45 mmol) in DCM (5 ml). After stirring for 15 min the mixture was washed with water and brine, dried and concentrated and the title compound was obtained in 135 mg yield. 1H NMR: 1.9 (d, 3H), 3.1 (s, 3H), 5.9 (q, 1H), 7.5 (t, 1H), 7.6 (m, 1H), 8.0 (m, 1H), 8.1 (t, 1H)
