METHOD OF SYNTHESIS OF 2-METHOXYISOBUTYLISOCYANIDE Russian patent published in 1995 - IPC

Abstract RU 2026857 C1

FIELD: organic chemistry. SUBSTANCE: product: 2-methoxyisobutylisocyanide. Reagent 1: CHCl3. Reagent 2: CH3COCH3. Reagent 3: alkali hydroxide. Conditions: medium - methanol, temperature of reagents addition is 0 C (not above) following by spontaneous temperature increase to 45 C (not above) and exposition at the room temperature. Prepared solid precipitate is treated with CH3OH in the presence of acid catalyst. Reaction mass is treated with ammonia and methanol and then - with alumohydride in the medium of diethyl ether. Prepared amine is treated with chloroform and alkali in the medium of organic solvent. M. p. is 72-73 C/65 mm mercury column, n2D

0 = 1.4182-88, d24
0 = 0.9020-24, RD: found 31.61, calculated 31.92. EFFECT: simplified process of synthesis.
