Reaction Steps

A solution of N-(2,2-dimethoxyethyl)-4-iodobenzamide (10 g, 30 mmol) in Eaton's reagent (100 mL) was heated at 135° C. for 17 hours. The reaction was allowed to cool and poured into ice water. The brown solid was isolated by filtration. Purification on silica gel eluting with dichloromethane gave 6.7 g of 2-(4-Iodophenyl)oxazole, 1H NMR (400 MHz, CDCl3) δ 7.79 (q, 4H), 7.72 (s, 1H), 7.27 (s, 1H).
