Reaction Steps
Following a procedure similar to that described in Preparation 5(i), but using 7.8 g of 2-propylimidazole-4,5-dicarbonitrile (prepared as described in Preparation 10), 2.14 g of sodium hydride (as a 55% w/w dispersion in mineral oil) and 17.1 g of trityl chloride, 14.6 g of the title compound were obtained as crystals, melting at 107° C. (with decomposition and with a yellow coloration at 102° C.).
