Procedure
To a stirred solution of N-(2,4-dimethylphenyl)-3-fluoro-N-isobutyl-4-(oxiran-2-yl)benzenesulfonamide (20 mg, 0.053 mmol) in ethanol at 25° C. was added 3-methyloxetan-3-amine (5.08 mg, 0.058 mmol). The reaction mixture was then stirred at 50° C. for 18 hours. Another portion of 3-methyloxetan-3-amine (5.08 mg, 0.058 mmol) was then added and the reaction stirred for a further 8 hours at 50° C. The reaction mixture was concentrated in vacuo and purified by mass directed autoprep (ammonium carbonate modifier). The relevant fractions were concentrated under a stream of nitrogen to give the required product, 11.2 mg. LCMS [LCMS2] Rt 1.25 min, m/z (ES+) 465 (M+H).
