Reaction Steps

In analogy to Example 83, step a) using 6-ethoxy-3-pyridinecarboxylic acid (CAS 97455-65-7) instead of 2-(trifluoromethyl)-4-pyridinecarboxylic acid (CAS 131747-41-6) and (+)-(R)-2-(4-Amino-2-chloro-phenyl)-morpholine-4-carboxylic acid tert-butyl ester (preparation described in example 91) instead of (+)-(R)-2-(4-Amino-2-fluoro-phenyl)-morpholine-4-carboxylic acid tert-butyl ester. Off-white solid. MS (ISP): 362.0 ([M+H]+)
