Participants

Reaction Steps

To a solution of (E)-4-(cyclopropyl(methyl)amino)but-2-enoic acid (2.00 g, 12.9 mmol) in DCM (60 mL) was added DMF (0.2 mL) and oxalyl chloride (4.42 mL, 51.6 mmol). The mixture was stirred at RT for 4 h and concentrated in vacuo to dryness to afford (E)-4-(cyclopropyl(methyl)amino)but-2-enoyl chloride. In a similar manner as described in Example 70, (R,E)-3-(1-(4-(cyclopropyl(methyl)amino)but-2-enoyl)pyrrolidin-3-ylamino)-5-(4-(morpholine-4-carbonyl)phenylamino)-1,2,4-triazine-6-carboxamide (85) was prepared using (E)-4-(cyclopropyl(methyl)amino)but-2-enoyl chloride. MS found for C27H35N9O4 as (M+H)+ 550.2, (M−H)− 548.3. UV: λ=248 nm.
