Reaction Steps

A procedure similar to that described in Preparation 4 was repeated, except that 2.0 g of 2-(indol-1-yl)-ethanol (prepared as described in Preparation 13), 4.81 g of 5-(4-hydroxybenzyl)-3-triphenylmethylthiazolidine-2,4-dione, 3.1 ml of tributylphosphine, 3.20 g of 1,1'-(azodicarbonyl)dipiperidine and 60 ml of anhydrous benzene were used, to give 5.69 g of the title compound, melting at 63.5-65.9° C.
