    • PROBLEM TO BE SOLVED: To provide a method for producing a specific hormone secretagogue and an intermediate capable of being used in the method.
      SOLUTION: This method for producing a compound of formula VI, comprises reacting a compound of formula IV with a carbonyl equivalent and CF
      3 CH
      2 NH
      2 in a reaction inert solvent to form a compound of formula VII, reacting the compound of formula VII with 2-picolyl-Z
      1 in the presence of a base and a reaction inert solvent at about -78°C to about 25°C for about 1 hr to about 24 hr to form a compound of formula VIII, reacting the compound of formula VIII with a suitable acid in a reaction inert solvent at about -30°C to about 25°C for about 1 hr to about 10 hr to form a compound of formula IX, resolving the compound of formula IX with D-tartaric acid in a reaction inert solvent to form the D-tartrate salt of a compound of formula X, reacting the D-tartrate salt of a compound of formula X with a compound of formula XI, a peptide coupling reagent and a base in a reaction inert solvent to form a compound of formula XII and reacting the compound of formula XII under standard t- butyloxycarbonyl group removing conditions to form a compound of formula VI.
