To a solution of 2-cyclopropylpyrimidine-4-carbonitrile (600 mg, 4.13 mmol) in ethanol (10 mL) was added sodium ethoxide (561.9 mg, 8.27 mmol). After 2 h, the mixture was concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure to afford ethyl 2-cyclopropylpyrimidine-4-carbimidate (400 mg) as a pale yellow liquid. The material was used without further purification.
