Abstract 1, 1‐Diphenyl‐2‐methyl‐3‐aminopropanol‐1‐ 14 C was prepared in a five‐step sequence of reactions from 14 (CO 2 and resolved into its d and l isomers in an overall yield of 9.5% based on carbon‐14. 1,1‐Diphenyl‐2‐methyl‐3‐aminopropanol‐3‐ 3 H was prepared by reduction of an intermediate with lithium aluminum tritide and resolved into its d and l isomers in an overall yield of 7.3% based on tritium.
