N-methylcyclohexanecarboxamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In 50 ml of ethyl acetate saturated with hydrogen chloride was dissolved 2.18 g of compound 137 obtained by Example 137, and the solution was stirred for 1 hour. Thereafter, the solvent was evaporated under reduced pressure, and the residue was recrystallized from methanol to afford 0.31 g of the desired compound (Compound 138). Thereafter, the solvent was evaporated under reduced pressure the residue was recrystallized from methanol
