Procedure
Following the procedures for Examples 339 and 408, 2-(2-isopropyl-5-methyl-2H-[1,2,4]triazol-3-yl)-4,5-dihydro-6-oxa-1,3a,9-triaza-benzo[e]azulen-8-ol and (S)-2-methyl-pyrollidine-2-carboxylic acid amide were reacted. The crude product was passed down a Isolute SCX-2 column, eluting with methanol then 2M NH3 in methanol. The basic fractions were concentrated in vacuo and the resultant residue subjected to reverse phase HPLC (C18 column, gradient 15 to 75% Methanol in water+0.1% HCO2H). The appropriate fractions were evaporated to dryness, passed down an Isolute NH2 column, eluting with methanol then further triturated in diethyl ether to give 402 as a white solid. LCMS: RT=2.79 min, [M+H]+=423. 1H NMR 400 MHz (CD3OD) δ: 9.14 (1 H, s), 7.93 (1 H, s), 7.69 (1 H, s), 6.05 (1 H, s), 5.99 (1 H, m), 4.51-4.50 (4 H, m), 3.70 (1 H, m), 3.57 (1 H, m), 3.50 (1 H, m), 2.36-2.33 (1 H, m), 2.10-2.08 (2 H, m), 1.63 (3 H, s), 1.56 (6 H, dd, J=6.63, 2.34 Hz)
