(2R,3S,4S,5R)-3-(3,4-difluoro-2-methoxyphenyl)-4,5-dimethyl-5-(trifluoromethyl)tetrahydrofuran-2-carboxylic acid, (R)-1-phenylethan-1-amine

(2R,3S,4S,5R)-3-(3,4-Difluoro-2-methoxyphenyl)-4,5-dimethyl-5-(trifluoromethyl)tetrahydrofuran-2-carboxylic acid, (R)-1-phenylethan-1-amine salt serves as a crucial chiral intermediate in synthesizing suzetrigine. This diastereomeric salt enables precise chiral resolution through crystallization, followed by amidation reactions to construct the stereospecific tetrahydrofuran core essential for developing targeted sodium channel blockers for neuropathic pain treatment.
