2-methyl-5-[[(2S)-oxiran-2-yl]methoxy]-1,3-benzothiazole → (2R)-3-((2S)-4-{[5-(2-fluorophenyl)isoxazol-3-yl]methyl}-2-methylpiperazinyl)-1-(2-methylbenzothiazol-5-yloxy)propan-2-ol

Reaction Conditions

Reaction Steps

To a solution of 3-[((3S)-3-methylpiperazinyl)methyl]-5-(2-fluorophenyl)isoxazole (28 mg, 0.10 mmol) in tert-amyl alcohol (5 mL) was added 5-[((2S)oxiran-2-yl)methoxy]-2-methylbenzothiazole (22 mg, 0.10 mmol). The reaction mixture was stirred at 95° C. for 1 day. It was then cooled, concentrated, and purified by preparative chromatography (1:19 methanol:methylene chloride) to afford (2R)-3-((2S)-4-{[5-(2-fluorophenyl)isoxazol-3-yl]methyl}-2-methylpiperazinyl)-1-(2-methylbenzothiazol-5-yloxy)propan-2-ol (M+1=497.27).
