Procedure

Preparation of example 175 from the title compound of Example 153 (38 mg, 0.072 mmol) and 4M HCl in dioxane (10 mL) was carried out analogously to Example 91. Isolation, also in an analogous manner, included freebasing with triethylamine and subsequent silica gel chromatography eluting with 3:1:1 hexane:ethyl acetate:ethanol. With ice bath cooling, the purified freebase in CH2Cl2 (10 mL) was treated with 4M HCl in dioxane (0.1 mL). After removal of the volatile components, the title compound (20 mg, 0.043 mmol) was obtained as an orange/yellow powder in 60% yield.
