Reaction Steps

To the product from Step 2C (400 mg, 0.9 mmol.) was added hydrogen bromide (45 wt % in acetic acid, 2 ml) and the mixture stirred until dissolution was complete (30 minutes). After this time, the orange solution was poured into ice cold ether (20 ml) and vigorously stirred for 10 minutes. The resulting precipitate was filtered and washed with cold ether to give the title compound (220 mg, 80%) as the hydrobromide salt.
