Procedure

A suspension of 1-{6-[(2,5-diamino-6-chloro-pyrimidin-4-ylamino)methyl]pyridin-2-yl}pyrrolidin-2-one (2.10 g, 6.29 mmol) in glacial acetic acid mL) and EtOH (24 mL) at 0° C. was treated with a solution of sodium nitrite (0.564 g, 8.17 mmol) in water (1.5 mL), stirred for 2 h, warmed to room temperature and the resulting precipitate filtered and dried to give the title compound (1.67 g, 77%) as an off-white solid; LC-MS retention time 1.99 min, (M+H)+ 345.
