Reaction Steps

(2S)-1-[(6-Fluoro-4-methyl-3-pyridinyl)carbonyl]-2-methyl-4-{[4-(trifluoromethyl)phenyl]sulfonyl}piperazine (may be prepared as described in Example 27) (67 mg, 0.15 mmol) was weighed into a microwave vial and dissolved in isopropanol (1.5 ml). Azetidine (0.203 ml, 3.01 mmol) was added and the mixture was heated in the microwave to 120° C. for 12 h with stirring. The reaction mixture was concentrated to give the crude material as a colourless gum (˜187 mg). This was purified by MDAP to give the title compound as a pale yellow gum (67 mg). The gum was redissolved in MeOH, water was added, and the mixture was concentrated under a flow of argon then dried in vacuo to give the title compound as a colourless solid.
