Reaction Steps

2-tert-Butyl-4-chloro-5-phenylisothiazol-3(2H)-one 1,1-dioxide (0.15 g, 0.53 mmol), 4-aminocyclohexanol (0.092 g, 0.80 mmol) and TEA (0.081 g, 0.80 mmol) was dissolved in dry MeCN (3 ml). The reaction was heated in a microwave reactor at 120° C. for 10 mins. A few extra drops of 4-aminocyclohexanol was added and the reaction was heated in a microwave reactor at 140° C. for 20 mins. The residue was purified by silica gel column chromatography using a 25:75 mixture of hexane and EtOAc, to give a 50:50 mixture of cis and trans isomers (0.130 g, 67%). The mixture was separated by HPLC (C8, 0.05M NH4OAc (pH=4.1):MeCN 1:1) to give cis (Example 38) and trans (Example 48) isomers.
