Conditions

Temperature: 50 °C

Procedure

Ethanolamine (1 mL) was added to N-cyclopropyl-4-methyl-3-{3-[(1-{2-[(2R)-oxiran-2-ylmethoxy]phenyl}cyclopropyl)amino]-2-oxopyrazin-1(2H)-yl}benzamide (Example 299a, 7.81 g) in DMF (3 mL). The reaction was heated at 50° C. overnight. The reaction mixture was partitioned between water and DCM. The combined organics were dried (MgSO4), filtered and evaporated. Purification by preparative HPLC (Xbridge column, eluting with a gradient of acetonitrile in 0.2% (v/v) aqueous ammonia) gave the title product (0.102 g) after solvent removal and trituration with diethyl ether.
