Participants

Reaction Steps

The enantiomerically pure ester from Example 6A (1.6 g, 4.21 mmol) was dissolved in 77 ml of methanol and admixed with 17 ml of a 1M solution of lithium hydroxide in water. The mixture was stirred at RT for 1 h and then concentrated on a rotary evaporator. The residue was diluted with 100 ml of water and acidified to a pH of 1-2 using 1N hydrochloric acid. The precipitated product was isolated by filtration, washed in succession with water and cyclohexane and sucked dry. After further drying in an HV, the title compound (1.1 g, 71% of theory) was obtained.
