Upon addition, the reaction vessel was sealed and heated up in a CEM-Discovery microwave at 150 Watts, reaching 110° C. in 5 minutes and maintaining this temperature 6 minutes. The reaction vessel was cooled to room temperature and the reaction mixture taken into methanol (5 ml) and purified by SCX-2 chromatography to obtain the free base as clear oil (50 mg). The hydrochloride salt was obtained following general procedures as a white solid (52 mg, 72% after salt formation.).
