Abstract
A practical and scalable process for the preparation of (1 s, 4 s)-4-(methylamino)-1′ H-spiro [cyclohexane-1, 3′-furo [3, 4-c] pyridin]-1′-one 2a, a highly functionalized and potentially useful building block for pharmaceutical research is described. The material is prepared via an efficient two-step sequence from readily available materials and is isolated as a single diastereomer in high chemical purity.
