Step 7: To a solution of 4-(1-(4-cyanophenyl)-1H-benzo[d]imidazol-6-yl)benzoic acid 6 (300 mg, 0.88 mmol) in DMF (5 mL) was added NMM (0.178 mL, 1.76 mmol) followed by HATU (501 mg, 1.32 mmol) at rt and the solution was stirred for 30 min. Morpholine (0.84 mL, 0.968 mmol) was added to the reaction mixture and stirring was continued for 16 h. The reaction mixture was diluted with EtOAc and washed with water and brine solution. The organic layer was dried over anhydrous Na2SO4 and concentrated under reduced pressure to obtain crude product. The crude product was purified by preparative HPLC to afford 4-(6-(4-(morpholine-4-carbonyl)phenyl)-1H-benzo[d]imidazol-1-yl)benzonitrile (100 mg, 27%, AUC HPLC 95.9%) as an off-white solid; m.p. 207-210° C.; 1H NMR (400 MHz, CDCl3) δ (ppm): 8.18 (s, 1H), 7.98-7.92 (m, 3H), 7.72 (d, J=6.6 Hz, 3H), 7.66-7.61 (m, 3H), 7.51 (d, J=7.9 Hz, 2H), 3.90-3.40 (m, 8H); MS (ESI) m/z 409.15 [C25H20N4O2+H]+.

What are people doing with this data ?

Pharma asks

1. What genes regulate xyz condition ? 2. What compounds regulate those xyz genes ?

An approach to answering these questions : chemical ontologies

Other approaches include• Computational chemical modeling• Similarity Ensemble Approach (SEA) • Literature-based discovery• Experimental high through-put screening

Chemical Ontologies

• Chinese, Japanese and Korean (CJK) patents now account for over half of all national patentfilings and hence are of increasing importance to patent informatics.

To demonstrate the importance of this …

• 1,740,040 distinct compounds were extracted from ~63,000 Korean patent applications - spanning from 1990 to March 2015

• Of these ~ 230,770 compounds were novel to Korean patents when compared tocompounds derived from US data - (spanning from 1976-March 2015)

• In the period 2006-2014, 46% of compounds appeared in a KIPO filing before a USPTO filing.
