Procedure

Starting from a mixture of (5S,6S)- and (5S,6R)-6-(3-chloro-1,2,5-thiadiazol-4-yl)-1-azabicyclo[3.2.1]octane described in example 63C, the chlorine was substituted with butylthio as described in example 14. A 1:9 mixture of (5S,6S)- and (5S,6R)-6-(3-butylthio-1,2,5-thiadiazol-4-yl)-1-azabicyclo[3.2.1]octane (10 g, 35 mmol) was dissolved in toluene (40 ml) and treated with potassium tertbutoxide (0.5 g) at reflux for 1 hour. The toluene solution was washed with water (15 ml) dried and evaporated. The residue crystallized with (+)L-tartaric acid giving the optical pure title compound in 12.5 g yield. (Compound 111). M.p. 128°-129° C.
