To a mixture of compound 404 (586.4 mg, 1.545 mmol) in tetrahydrofuran (20 mL) was added lithium aluminum hydride (240.5 mg, 6.34 mmol). After 1.5 hours at reflux the reaction was cooled to room temperature and quenched with water (240.5 μl), followed by 1N NaOH (240.5 μL), and then water (2×240.5 μL). The remaining solids were filtered off, and the filtrate was concentrated to give compound 405 (406 mg), as a sticky white solid. LCMS-ESI (POS), M/Z, M+1: Found 171.1, Calculated 171.1.
