Reaction Steps

To a solution of 447 mg (1.6 mmol) 2-(2-methoxy-3-methyl-4-trifluoromethyl-phenyl)-4,4-dimethyl-4,5-dihydro-oxazole in 4 ml nitromethane was added 0.78 ml (12 mmol) methyl iodide and the mixture heated in a sealed tube to 60° C. for 18 h. The brown solution was diluted with tert-butyl methyl ether, the suspension filtered and the precipitate washed with tert-butyl methyl ether and dried. 2-(2-Methoxy-3-methyl-4-trifluoromethyl-phenyl)-3,4,4-trimethyl-4,5-dihydro-oxazol-3-ium iodide was obtained as off-white powder: MS (ISP): 302.1 (M+).
