A clear solution of 3-((phenylsulfonyl)methylene)oxetane (450 mg, 1.284 mmol) in methanol (10 mL) was treated with 1-benzhydrylpiperazine (389 mg, 1.541 mmol) and stirred at 50° C. overnight, more 3-((phenylsulfonyl)methylene)oxetane (100 mg) was added, stirred at 50° C. o/n, concentrated. The crude was purified by ISCO (40 g), eluted with EA:HX=0-50%, the deired fractions were concentrated to yield 1-benzhydryl-4-(3-((phenylsulfonyl)methyl)oxetan-3-yl)piperazine (670 mg) as a white solid.
