Ethylamine (g) was fed into a stirred soln.of 318 g II in 300 mL MeOH with addn. of 15 mL ethereal HCl at 55¡ã. After feeding 314 g Ethylamine, the mixt. was held for 15h. Then, MeOH was distd. in vacuo, the mixt. was dild. with 300 mL C6H6, the soln. was filtered, and C6H6 was distd. in vacuo. The residue was dissolved in 480 mL Me2CO and acidified to pH 1 with ethereal HCl. After cooling for 15h, the ppt. was filtered to give 240 g I (62.2% yield).
