A solution of 8 g. 2-chloromethyl-4,5-diphenyl-oxazole (prepared as described in Example 1 a) and 6.6 g. n-butylamine in 100 ml. anhydrous benzene was refluxed for 4 hours. The reaction mixture was washed with water and the separated benzene phase was distilled at 20 mm. pressure. The oily residue was dissolved in 100 ml. anhydrous ether and a flow of gas hydrogen chloride was bubbled through the resulting solution. The 2-n-butylaminomethyl-4,5-diphenyloxazole hydrochloride was recrystallized from absolute ethanol/anhydrous diethyl ether: 7.4 g., m.p. 120°-123° C (yield 72%).
