Reaction Steps

(R)-1-(N-Benzyloxycarbonylpyrrolidin-2-yl)-3-hydroxypropene and 2-bromo-4-methylaminosulfonylmethyl-N-trifluoroacetylaniline were used. Column chromatography using elution with 4% acetone in methylene chloride afforded the title compound as a white foam (44%): FAB LRMS (m/z, relative intensity) 620 ([MH+ with 81Br], 618 ([MH+ with 79Br], 98), 576 (50), 574 (63), 512 (17), 484 (33).
