Procedure

Compound 194 (1.00 g, 2.33 mmol) obtained in Reference Example 133 was dissolved in 10 ml of tetrahydrofuran. To the solution was added 6 ml of 2N hydrochloric acid, and the mixture was heated under reflux for one hour. The reaction solution was neutralized with a 2N aqueous solution of sodium hydroxide under ice cooling. Water was added thereto, and the deposited crystals were collected by filtration. The obtained crude crystals were recrystallized from methanol/water to give 291 mg (yield 32%) of Compound 196 as a yellow powder.
